I think it would sell at that price. People always ask way to much for this stuff now days, so $25 should be an attractive price to most looking to build an S7 system.

I'd tend to agree. People in the UK would probably charge at least $50 for that, hence people like me buying from the US more often than they otherwise would. You could be cocky and probably pull in a little more, possibly, at least over here, not sure.

I've done nothing useful today. Boring things like shaving my head and doing laundry, though I did dig up some ancient code and stuff I made for a Duke 3D mod;

This came about over on Duke4.net when somebody began discussing whether the Build-based Bombshell prequel should have working toilets and I remembered having written such code for a mod long ago. Pointless, right? Yeah, well, you're looking at the guy who thought making a lawn mowing simulation mod set in 1950s suburbia was a good idea, so something like this was bound to happen.

Nope... I will not let it go for more than what I think it is worth. I like it better, when I know I made someones day.
Speaking of K6... I am under my lucky star at the moment, this for 43 US Dollars.
Unisys is like my favorite brand of computers. IBM are just so overrated... Just so meh' compared to this.

I definitely approve of this purchase. Good price indeed. Nice shape and looks to be mostly a nice original piece. Looks like an external SCSI connector there. Makes me think the hard drive might also be SCSI.

It is ready for SCSI upgrade, though originally it came with something like a 170 or so megabyte IDE drive.
It has been upgraded from 8mb ram to 20mb ram. Other than that, it is factory original.
The motherboard has a 486sx25 CPU, yet this is upgraded with a 33mhz CPU in the "overdrive" socket.
Is it possible to install a standard CPU in an overdrive socket? If so, then I will guess at a 486dx33 installed.
If it can use such a CPU, then I might pop in the Dx2-66, and my VLB machine will recieve the Dx2-80.
My FIC 486 VIP IO will then be getting the Dx4-120 and a CL-5446-2mb GFX card. So....
Basically, I will be having four 486 class systems. Not bad, as this is my favorite era of all.

Looking at pictures of the mobo from the Unisys 4253 model, I do not see any barrel battery.
My old 286 Unisys (PW/2 Series 300) has no onboard battery, and is only using an external one.
I am hopefull that this has one of those, and not barrel or Dallas. Other than that I am happy with it.

What will be next? One of those extremely massive Unisys 386 systems? That would be cool.
I find the design of Unisys (286 to 486) in the same league as old big box Amiga's.
Inside them, the build quality are just so overenginered. They are essential IBM's with Amiga design.

EDIT:
Yes... It can run a Dx2-66, has S3-806 onboard gfx and supports 72-pin memory. I like it.
Info on this machine...

I have zero experience with Unisys, but I agree with the IBM sentiment, far too limited and just generally awkward at best. I'll always prefer self-built machines above all else, but this thing looks cool.

Not sure what that card with the two 15-Pin connectors does.

My mother was a tech-designer, working with high voltage stuff.
She used to draw powerstations in autocad, drawing high voltage transformaerstations and have been heavy
into drawing layouts for powerlines between Sweeden-Denmark and possible contributing to lines between
England and Denmark too. If they have been layed out.
In the late 80's and up to the middle of 1990's, they only used Unisys stuff when using AutoCAD.
Yeah... Unisys are true workhorses, build to take some serious punishment.
They feel like the result of a Porche having had sex with Tiger tank from WW2.
I can't describe them more in dept, they just have to be experienced up close, in order to know what they are.

Well the dual PIII P2B-DS starting acting up again, but this go around with blue screening under load. Strange how you can run through hours of benchmarking and testing, let a system sit for a couple days, then everything just goes to hell in a handbasket. I spent most of Saturday dicking around with it. I plugged it in to try IOQUAKE3 on this system as it was suggested as a version of Quake 3 to try as it supposedly has better SMP support. Well it doesn't look like IOQUAKE3 will run under Windows 2000, even after upgrading to unofficial SP5 and installing .net 2.0 which appears to be the highest .net that will install on 2000 as I tried later versions and they all complained they were for XP or later. Anyway bluescreening started while trying to install SP5, so it's not because of SP5 that this issue started. I did a run of 3Dmark2000 and it wouldn't get through it, just kick back to the desktop within a few minutes, and playing videos on Youtube resulted in BSOD within minutes, as well as running everest's burn in test on the cpu. I started thinking about the power supply I had in the case, thought it was a 250W unit, turned out it was just a 145W jobber, so I thought, well there's the problem. Put in a 430W Antec Trupower unit, which I know is solid, problem still remained. The BSOD seemed to be getting progressivly worse as time went on as well. So I pulled the board out, and noticed one of the brackets that hold the heatsink on was hitting one of the tall capacitors ASUS placed way to close to the socket and wasn't letting the cpu seat all the way down. So I fixed that little issue as well. I had put a thermal pad between the NB and it's heatsink, but decided this time to just remove it entirely, slap on from real compound and put the HS back on. System ran for awhile, same problems came back. I felt the ICS9150 gen and it felt quite hot, and at one point the system BSOD'd as soon as SoftFSB upped the FSB on boot, so I am like, ok maybe the clock gen is unstable at 133 when it gets hot. So out comes a heatsink to slap on to that. Well after all of this, issue still happened and the user profile decided to corrupt itself. Interesting though after I rebuilt the profile, the random erros I had with SoftFSB loading seems to have gone away, and the system has been making it through several benchmark runs as well as video driver changes without issue. So I have absolutely no idea if ANYTHING I actually did fixed it or if it was something with the profile ( I have no idea what if it was ) or if whatever rag the motherboard was on at the time just fixed itself. At one point the system would only make it through a run of 3DMARK2000 if I overclocked the video card. Now that's strange too. I did bump the PCI latency back down to 64, then upped it to 128 after the system seemed to be back to some sort of stability, so maybe the PCI latency of 255 was the issue? Not sure, I haven't had that problem before with PCI latency if it was, but first time for everything I suppose.

After SP5, now UT will not run in Direct3D. Reinstalled and tried different driver versions, reinstalled DirectX including dropping down to 8.1b, and reinstalled the game. None of that fixed it. The game runs extremely delayed in D3D mode. Mouse movement takes about 30 seconds to respond. I had this issue pop up with the Radeon 7500, but only after installed the Geforce 3, then going back to the Radeon, but this time I was unable to clear it up except to switch to OpenGL mode.

Another thing is, now some of the benchmark scores have actually gone up, and some have gone down. 3Dmark2000 shows nearly a 1000 point increase now, with 2001 dropped by about 200. Quake 2 dropped from 255fps down to 212, but Q3 in SMP is a couple fps faster, while non smp is actually slower than before. Very ODD indeed. Microsoft obviously changed something in 2000 at some point with updates, since SP5 is just a culmination of updates, that seems to strangly favor 3DMark2000 and makes for a wider gap between SMP and non SMP, albeit seems an artificial gap more than anything. These are things you'd never notice really back in the day unless you were really doing heavy benchmarking I guess. I never realized this stuff when 2000 was king on shit hill.


So given the strange behavior of this motherboard, I will probably most likely just resell the board. Dual Xeon PIII is going to be tricky to find a way to hold these massive chips in the board, and I will have to run PCI graphics, which isn't the end of the world mind you. It looks like the Parhelia PCI-X card's are't terribly great performers anyway, and looks to be beaten by a nvidia 6200 pci card, which I have, along with an 8400GS which I already know can pull into the 150's in Quake 3. So not having that card, and the other PCI-X options are either not attractive or way to over priced and still not attractive performers, I am fine with PCI graphics for the Xeon.

Dual PIII is not out of the picture yet though, I also will be trying a pair of Tualatin's on this board that I also picked up which already have socket370 adapters on them. If they don't work on this Abit VP6 board, which there is a good chance it won't actually, I can resell these chips very quicky and easily.

Edit: "Kernel mode trap" after a couple runs of Quake 3. ya, not stable. It's odd, once it cleared itself up last night, it ran for hours without issue, and now the problems are back. Well, maybe the caps on this P2B-DS board are failing. IDK.

@Brostenen; Your mother had an awesome job. Yeah, you really don't see over engineered machines so much anymore, some of these old chassis and the parts in them look as though the designer were trying to build something that could survive several nuclear wars before going wrong.

@WaybackTech; No way! It's a VP6! In the early to mid-2000s I knew someone running that board, I swear it was that one despite my friend listing it as a "BP6" in the old spec list he wrote back then when keeping track of our systems. I remember being almost furious that it beat my Duron and worse still, it was owned by his girlfriend. Yeah, I got beat by a girl, with one of those motherboards. Rats.
For the record, the BP6 only ran Celerons, though was novel for the fact it ran two. I know for a fact the girl had Pentiums installed, so either the board was modded or my friend wrote the list wrong. My memory has always been that of the VP6's layout however and there are other known errors on the list.

They seem to become a little awkward at higher speeds, these Slot 1 boards. Mine becomes similarly problematic when run at higher FSB speeds than intended and even then, it still has the odd kick off about microcodes and such now.

Waiting to see how your build goes before I give any thought as to whether I really want a Slot 2 or not.
You may be able to get tie-wraps through the holes at the sides of the slots and use a third to draw them together over the CPU before pulling them tight? Did something similar with a P2 that was missing its holder once but the heatsink had convenient lugs to hang them onto.

#Waybacktech:

Yeah... My experience with P2B-DS, are only negative as well. My board booted fine with a single Celeron-266 in CPU slot number two, and it would freeze right before the POST bip. It would not even come to life with a CPU in slot number one. Not even P-II-300 would run at all.
P2B-S on the other hand, has never ever let me down. It is 100% stable and runs really well with a P-II-350.

What a beast that dual 370 board you have there... Looks good, and you even got raid!? The only board I have with raid on it, are the Asus A7V266-E.
A really nice board too, that I can only recommend to everyone that are searching for Win98 equipment between mid and high range 98 boards.
Sadly it is not a dual-cpu board. Would have been so cool.

For me today.... I have found the users guide for the Unisys machine. It took me just under one hour to dig out of "the electric spiders-web".
What a bad boy... Roughly 200 pages, covering the 3 and the 5 expansion slot versions of this machine.
Found out that the 5-slot has VL-Bus and both versions can be upgraded with Dx2-66 CPU's. Damn it... Never read that stuff. Now I want the 5-slot.

Yeah... We are not at all jealous of him, are we? Nono... Not at all. No way we are. Nope. (well... I am jaelous. I want one too) :-D

True those 286/386/486 Unisys machines are capeable of being nuked more than twice. I so hope that you will get one too in the future.
As far as I have understood it. Unisys never used barrel or dallas batteries in their systems. They used those long lasting Tadiran batteries.
What a statement to forward thinking.

I like the toilet mod btw paul. Every game that has a toilet should be usable IMO :-)

This VP6 comes with a pair of 1000/133/256 PIII's already, which are somewhat harder to find and more expensive even in S370 version, so at the very least it should be on par with the P2B-DS in performance. He did have a 3DMark2000 score on his listing of 5209 ( I think it was ) which is a tad lower than what I am getting out of the P2B-DS ( when it runs that is ) and no mention of what video card he used to run the benchmark so I am hopeful that even if I am unable to make the board run the pair of Tuallies, which posts from years past suggest only 1 will run on this board, not 2, well I will just use the chips that are currently on it now. Dual Tuallies would be fun to play with but not a big deal. I did look for the 1100/100/256 PIII S370 chips, and the 1 currently on ebay they are asking a small fortune for it so that for me is out of the question as a processor to run on the P2B-DS in pairs with appropriate dual cpu slotkets ( which I actually have one but would have needed another ). I really love the P2B-DS if it wasn't for these damn random moments where it just says to hell with the owner. I am GOD as far as the computer goes damn it, and it is sinning against me! God's judgement is upon the P2B-DS unfortunately :-) But who knows, maybe the VP6 will turn out to be a big POS as well... it is a VIA chipset after all... The seller accepted my offer for $45 which is more in my comfort zone, though the guy was asking like $29 shipping, which is why i knocked him down from $60. Probably could have gone a bit lower but I think for the package as shown in photos with I/O shield included, it's still a good deal.

If the damn motherboard for the Slot 2 would ever get here... it will be in my hands by tomorrow night though. I was thinking about strapping those down but the weight of the processors plus the heatsinks screwed to it, I don't think the straps will hold it very well but it's an option. I was thinking about trying to modify some slot 1 brackets enough to hold them. "Bench testing" the board should be fine just shoving the processors in, but once ( or if ) it goes into a case, gravity will be an enemy. These chips are roughly the size of 2 PII's and the processor core is quite a bit larger than a normal PIII, which given these are 2MB versions makes sense. There is a lot going on around the top half of the chip but I haven't removed the heat spreader yet to take a look at it. Interesting though the heat spreader on these is attatched the same, and use the same clips as AMD Athlon slot A cpu's. The plastic back just has a couple clips on each side that snaps it to the HS, just pops right off.

Nuked more than twice.. lol I kind of feel that way actually about my Compaq XL560... built like a brick shit house.

It's horrible code, simply horrible. I will never get back the 20 minutes I spent making that work. Said code started in a horror mode I worked on, but only as a joke and it acted as a restore point, it served its purpose and allowed me to test some systems I had implemented. It was ultimately removed from there because it was never meant to stay, more conventional restore points replaced them. The code was re-used about 4 years ago in a mod I never completed, the one that level belongs to, mostly as an homage to the very game it was a mod of, but being a female lead she couldn't just stand there for obvious reasons. It still gave a health boost (as with regular Duke 3D) and it added to the game mechanics because the mod had stealth elements, the flush could alert nearby enemies. There was also a very small chance that upon use an explosion would occur for no reason, just because I felt like being evil. As per the discussion on the Duke forum and out of boredom, it has had one last revision, it is still broken (some audio timings and the player locking are slightly out) but this is the last time I'm touching it, 20 minutes of my time was more than enough.

Almost sad to see my once great Sci-Fi stealth mod turned into this, how bloody constructive. At least it provided me with a few laughs. Still, I agree, which is why everything I've played gets "the Duke Nukem" test where I hammer the use button only to be disappointed.

Good luck with the VP6. The 1100/100 chips are definitely not common now, I doubt if they ever were, and the prices were going up when I snagged mine. May be worth giving CPU-World a shot? Of course it would be advisable to buy from a known reputable trader there and not some newbie who has never sold anything. I was waiting a very long time for mine as the initial pair I found cheap was snapped up by someone else, someone I knew so it wasn't so much a problem because they got used, but it was a long wait. A few popped up from time to time at a high price and then one day a British seller put two unused chips on for a price I was comfortable with. Still, if only Intel didn't insist on fixed multipliers.

I am GOD as far as the computer goes damn it, and it is sinning against me!

That made me laugh. Maybe the computer worships a different god? Perhaps it believes you are a false deity and is yelling something that rhymes with snackbar every time you try to run things. Strangely, my K6 is still working properly and I'm still not 100% sure what was really wrong with it in the first place. Even the POD is still working which is especially strange because it is an incredibly precarious machine at the best of times.

I dunno, those tie wraps are quite hardcore, I'd be more worried about warping the board really now that I think about it. Perhaps you'd have to fashion a backplate for the board such as those placed behind waterblocks, I'd imagine such a thing could be fashioned with hardboard or something if it was required, even if it is a bit of a bodge. Admittedly the mounts for my P3 are missing, they were in the bottom of the P2 case so now the processors can fall out if the system is moved. Luckily the power cable does a good job holding them back.

The 560 XL is very solid, a lot of the Deskpro's were. I still have fond memories of those P2-400 models where I worked, they had to be at least 2mm steel throughout if not more.

LOL oh come on Paul, that's some funny shit right there man. Since being a T-girl is like the "in thing" now, seems like the mod might actually make some sense in our world now. Doesn't matter really though, male or female character, still funny as fuck man. LOL I am sorry but the sounds were fucking hillarious and piss puddles... Oh that adds such a fun element to the game. I can just see this mod being used for online death matches... lock the player on the crapper adds a bit of risk when other players are hunting for kills. Take a leak and maybe get killed, or don't and have your bladder explode... that would be hillarious to see.

Well... I was on ebay again this morning. I swear I wasn't looking for this, or anything like it. I was actually just looking for processor brackets of some sort to use with the Slot 2 processors. It is very strange what ebay puts in the list of results. Never the less, this was only $25.... and is a very unique motherboard, which is right up my ally in general. Dual S370 on an Intel 815EP chipset. From what I can tell, this Acorp company was the only one to actually produce a motherboard with a "hacked" 815ep chipset to work in dual cpu operation, which upset Intel a bit apparently, which I also like. Looks like it uses a jumper free bios of some sorts as well. Pair of, yet again, 1Ghz P3's, coolers and 512MB of ram. One thing I noticed looking at the layout of this motherboard is that it shares a similar design to the VP6. The VR section in particular is very similar, uses the same brand of capacitors as well. I kind of wonder if Acorp teamed up with Abit to produce this board in some way. White AGP slot too, that's kind of unique.

It is also a similar trick to that VP6 I mentioned, SMP where SMP ought not to be. I feel bad for the chipset in regards to the airflow from those coolers. Now I think about it, my Dual P3 also came with 512MB originally, only had 500MHz CPUs though.

Well, for $25 you probably can't go wrong.

I did nothing computer related today because I wasn't at home, but I did obtain a new shirt or two due to some of mine becoming increasingly thin;


And a couple more which are equally offensive to the eyes, I have no idea why, but I've always had rather a liking for excessively loud shirts. Also ordered some new linen trousers because mine are missing, but those are boring so I won't post them.

The first shirt there makes me think of one thing very quickly, CGA graphics. Another one has an interesting motif on one of the panels;

Which looks oddly similar to an early version of my channel graphics.



On the other hand, I have decided now that the Athlon XP is definitely next for a video so I'll be tidying the script up soon. As my Pentium OverKill is also working now I will be looking into doing that follow-up on the NexGen at some stage after that, but I may put the Pentium D and Xeon between those as they're long overdue for a video now.

I kind of like those shirts. Sure can see the CGA theme going on in the first shirt for sure.

Well the Slot 2 motherboard was hand delivered to me last night. Unfortunately I have been unable to get a POST out of it. I suspect the VRM's are at fault, though I can't quite place down why for sure, other than they are just not compatible. Intel's manual states the board can use either 5V or 12V VRM's and does not call out any specific part # or amp rating for the VRM's, simply states either can be used and to use the 12V to provide more power for accessories if necessary. The VRM's I picked up are VXI Slot2 universal which I think auto adjust for either 5V or 12V as they state they are 5V/12V. I think that is where the problem is though as the processors remain stone cold even after several minutes of being powered on. The motherboard is aware though because it does beep an error code when the processors are removed. So anyway, that's where I am at for the moment with that project.

This site specifically lists the VRM compatible for the C440GX+ motherboard. This VRM also covers the same motherboards as the universal VRM I purchased covers, except the universal is not listed for the C440GX+ - http://america.hongfaith.com/cpu_related/Accessories/VRM/073-27042-...

So I ordered a pair of these - http://www.ebay.com/itm/371434286634?_trksid=p2057872.m2749.l2649&s...

same seller I bought the other ones from, which look exactly like the universal ones, and I saw these as well before and I was going to purchase this, but when you see another listing as "slot2universal" kind of makes you think there is a better change of them working. Anyway so, if this doesn't bring the board to POST, then I guess either the seller lied when saying the board works great, or I have another problem going on. We shall see in a few days...

While searching for a VRM, I stumbled across a listing for a quad slot 2 xeon motherboard with processors, brackets, and vrm's. Thought you might like to take a look at it Paul. Looks like it has some integrated capture capabilities. Very interesting workstation board - http://www.ebay.com/itm/200884163074?_trksid=p2055119.m1438.l2649&s...

I've been quiet because I had a headache and then I had more boring things that needed doing. I then come back to discover that some of my Banjo Kazooie videos have Left and Right channels reversed. This makes no sense as they were often recorded back-to-back with no changes to the mixer or wiring. It is of little concern as rendering 480p is small fry for the Xeon (it can render the entire Let's Play in around 2 hours if not less) but it is a bit tedious running around the timeline trying to find where the channels reversed. I'm stumped as to why, possibly I hit a switch somewhere without noticing. I was tempted to leave it and blame people's speakers, but I'll fix it instead.


Good luck with the VRM problem, hopefully your board actually works.
That is a beautiful board, I wouldn't be able to house it in a chassis properly though and as is often the case, no UK shipping. It appears to be from an SGI 540 which would explain the video interface, SGI were always inclined towards Video/Graphics/Modelling after all. I'm probably taking a break from building until I catch up anyway, plus I want to put time into stabilizing the Pentium D as my repairs were barely enough to get it through the end of Mirror's Edge.

Recieved them two machines today. The K6 is actually a K6-II running at some 233/322 (not shure) mhz.
I just had a small peak and clearly saw something with 3 and that it was a K6-II.
Then I realised that it was extremely dirty, and took it apart. Tore down the case and gave it a good clean.
Stored the motherboard, with cpu and memory in an antistatic bag for later testing.
Other than that, a standard onboard sound and a matrox mga card. Floppy, 10gb HDD and HP Cd-Burner.

I only opened up that Unisys, and found that indeed there is a Dallas battery on it. Not tested if it still works.
Before that, I need to take it apart and inspect everything. What I did find, was that the harddrive is a SCSI.
Yes sir.... 50-Pin SCSI drive. Wich is really interresting. I can't see how big it is, because it is mounted under
all them drives. Then I took a look at the long card. It is a strange one, and it is made in Denmark.
I have absolutely no idea on what it is. Hardware made in my country!! Hmmmm...
The only thing that I can think of is that it must be some kind of communication card or something like that.

Got some pictures of that full size isa card. Absolutely no idea what it is..... Well... I know for shure it's made in Denmark.
Though..... What is it? Netcard? Controller for some kind of equipment? Something else?

I'm surprised to see the K6-2 was available as low as 200MHz, I always think it started at 266 - even the user title feature on this board switches to "K6-2" when 266 posts are reached. 322 doesn't seem likely as I've never seen that marking and it would require a very strange multiplier. That sound, I think, is a CMI8738 which is an OK-ish solution in its own right, not something you'd use on a system that has working ISA slots though. Irrelevant as you're putting different innards in the case anyway I guess.

The dreaded Dallas clock. Kinda sucks that the different brands built the insides differently, yeah, the ODIN and Benchmarq models are different and have the battery and crystal in different places to the Dallas one, they're also not interchangeable in some boards, such as how my K5 won't take Benchmarq chips. Horrid things. Woo! SCSI for the win! I have always really loved SCSI, such a bulky interface yet somehow very satisfying to see working in a machine, something about it just says "Yeah, this is serious now, screw you IDE." to me.

Communication would be my guess, at a guess I'd say something passed through it in a daisy-chain or ring-like topology, but what protocol and for what purpose I still don't know. It's still odd to me when I see cards made in the UK, I have a satellite broadcast card which was made here, powerful but the drivers were licensed heavily and cannot be found anywhere, the company is long defunct.

That is a thick ethernet 10 base 5 controller. Same card but with a token ring connector - https://www.amazon.co.uk/COLLECTORS-Dataco-Denmark-PC-1115-2938/dp/B...

The AMD AM7990 shows up as an Ethernet controller, but this isn't confirmed. The Hitachi chip is a controller of some sort, but what catches my eye is the "DES CRYPTO" under that socket, sounds like serious kit, presumably DES encryption; https://en.wikipedia.org/wiki/Data_Encryption_Standard

Probably not much practical use, but it'd look good on a wall if nothing else.

Edit; WaybackTech beat me to it and would seem to confirm that the AM7990 is an Ethernet controller chip.

Token ring, encryption.... Hmmmm.... It has both male and female 15-Pin.
Could this perhaps be an interface card, for a creditcard terminal system or something?
