It should be practically indistinguishable from the original OPL2 AdLib card, interested to know where the noise floor sits though, doubt it's gonna be great as the YM and YAC chips seem to be noisy on their own in my experience.

There are another alternative OPL2/Adlib clone, sold from UK. It is a kit/diy product. here

As for me. I have been doing some metal work on the case that will be the Amiga500 boards new home. It really need some touching up, yet it is the first time, that I use one of those rotary cutting tools. It is a dremel type of tool, made by skil.

My case convertion is almost done. In order to make it a fully functional machine, then I need to find a way to hook up a keyboard. Then it will be as functional as a stock Amiga500. After that, I need to make some upgrades to the machine. Like scandoubler for VGA output, combined 8mb Ram and IDE board for better useability and IDE devices. I need to get a kickstart switcher installed and finally I need to install a boot selector, in order to be able to boot from external drive.

Well...
Yesterday I had this baby fired up for the first time. I watched demo's and played games that did not require a keyboard. And had a six pack of beer, because of the work that I have put into this.

How did I do?

That looks very nice! I assume you cut out the port area? That material looks thicker than on most cases, must have been a pain. Did the offsets of the screws work out for you?

Thanks.
The case was actually hard to cut. I removed a strip under the PSU thus making the horisontal hole longer. The I used a piece of cardboard, because the board needed to be raised a bit. Cut the bottom RF shield in order to make it fit the case inside. Poking holes for the brass standoff's. Grinded the screw part of the brass standoff's and glued the standoff's and the cardboard to the case, using some epoxy two component glue. That way I had something that I am able to fasten the board on, using normal PC screws.

So the shiny metal you see at the ports, are actually the original RF shield. The case is actually an old 486 case from a dead Unisys machine. It originally came with stuff like a DX-33, onboard S3-805, VLB and SCSI. The faceplate of the case was badly yellowed, yet nothing that a melanin spunge can not take care of. Now it is only aprox 10 percent yellow, compared to before. No retrobright, only this spunge that I suspect is the same as the magic erasor spunge that you will find in America.

I still need to find a keyboard solution, find an internal scandoubler and get an internal IDE controller. However, I have upgraded it with a kickstart switcher. It is a 4-way switcher, originally made for Roland gear. As of now I have Kick 1.2+1.3+2.0(37.350) original roms installed on that switcher, and the switching turn-knob are mounted on the backside on a slot-bracket.

This is what that AdLib clone sounds like;


It uses pretty much identical components to the genuine card, so sounds the same. The noise floor is surprisingly low, probably as good as you can get with Yamaha's crappy chips.

Bought something for my Amiga500-Desktop project. It is product that are in picture two from the top, on the following Amibay page.

IDE + 8mb FastRam

I need more upgrades, for it in the future. Yet with this, I can use a HDD and a CD-Rom drive. And I will be getting 8mb of Ram.
In the future I have to invest in a scandoubler, in order to use modern flatscreen monitors, and I think that I will be getting a USB keyboard interface
as well, so I can choose between a real Amiga keyboard or a USB PC keyboard. Perhaps I will be getting a boot selector and perhaps a clockport.

Once this IDE/8mb is installed and I have a keyboard connected, then the basic machine is done.

I rode my antique bicycle to Hornsea a few weeks ago (by all means search Hull to Hornsea on your favorite maps thingy). Meanwhile I haven't been motivated to work on any videos because OS updates have crippled my workstation, everything is slow, Vegas crashes, I have no sound outside of a USB mic, but I am still playing with hardware behind the scenes. Currently trying to mess with ALI chipsets as I know very little about them but the Socket 4 board I have with their chipset was DOA, strangely the same failure mode as several other boards on the 'to repair' pile which are all around the same age, I lean towards quiet tantalum failures as they all have those onboard.

My workshop computer is currently a Celery 2 Doodoo that I picked up from the piss pile (pile of trash at the end of the street) and it barely works, it needs replacing. Now I feel old because rather then meticulously pick out parts, I'm just going to buy a cheap AIO from earlier in this decade and have done with it, it ought to do well enough for playing music, putting a video on in the background and other small tasks like that. Will likely update once I choose one. Right now it's between a HP or an RM, the RM has better specs and is slightly cheaper, but comes with no OS, keyboard or mouse, overall I'm leaning more towards the HP on the basis that it comes with these things and can simply be upgraded later if it starts feeling slow. It has to be better than the E8200 out there right now, there's no way an i3 3220 can't outrun that shit.

That is a really nice trip you made. I am glad that you have gotten over that back to the extend that you can ride long trips again. Wonderfull countryside you have been through. It reminds med of the island of fuen, on were I grew up. Mostly flat, and just perfect.

This is an areal photo of my childhood playground (the forrest it self), and as you can see, the countryside is pretty much just as flat.

I did a search on the route you took on that bike, and I must say that I am deeply impressed by how far you went on it. If you for some reason decide to come to Denmark, then I will be happy to take a long bike ride with you, and have the backpack full of beer, water and lots of food.

Well...
I just recieved that M68K Ram/IDE adaptor. It is an adaptor, that you install by sandwiching it between the motherboard and the CPU on an Amiga500 og Amiga2000. I am not sure it is compatible with an Amiga1000. It is a rather strange device, compared to an IBM compatible PC. However. There are two signals, that need to be fed into the adaptor, that are taken from the motherboard. It is the signal lines called /INT2 and /OVR (whatever /OVR means), and for that I have to solder two jumper wires onto the Amiga500 motherboard, and attach them to the adaptor. Finally I have to use a kickstart rom, that has SCSI.DEVICE in it. Kind of a driver if you like. For that I can patch an kickstart 1.3 rom file and then flash it to an eprom chip. Or I can just use a rom that have it build in. As I am constructing an 500 kind of machine, in were I am aiming at compatibility and as many features on top (not speed centric at all), then I already have this kickstart switcher with 3 roms on it. And one of them are the 2.0 version 37.350 that have the SCSI.DEVICE build into it. The bad part is that it will not transfer faster than 1mb/s. Yet the aim is feature/compatibility centric and not speed centric, so it is ok with me. And I do have my Amiga500/TF-530 already build.

Next step, is to get a scandoubler for my desktop-500, and then figure out what to upgrade it with. Perhaps install a PC-Card that will allow me to run an XT-class machine on the Amiga. Perhaps aim higher and have a 286 class PC-Card upgrade. That would be a nice machine with lots of features.
