The YRW-801M instrument ROM is already dumped. Could you peel off the "MIRO" sticker on the chip at U12 and see what the markings are? (It'll likely be a micro controller of some sort).

Ahh, ok. So yeah, there's likely nothing to dump from that outside of the instrument ROM. The 82c929 is an HLE SB16 + CD-ROM interface (a data sheet with register programming info is available), the AD1848 is the DAC for the SB16 audio, and the OPL4 handles the rest. So we don't need the card itself for emulation, just the drivers and whatever other software came with it.

Drivers and manuals are on the site I linked to:

http://www.mirosupport.de/sound/pcm10/pcm10.html

They also carry files for the PCM12 that has a built in MIDI port and can support a wavetable extension

http://www.mirosupport.de/sound/pcm12/pcm12.html

In a later incarnation it was PnP compatible

One of the most famous demoscene Easter Eggs. Great soundtrack on the demo itself too.

Tried to install OS/2 Warp 4 in at486 on a lark - the installation claimed to complete but after the "thanks for installing!" screen I got a big red error screen that said the installer couldn't get the installed hard drive letter. I'll see if I can figure out what's going on with it.

If you really want some funky PC hardware, I've got a Commodore A2286AT bridgeboard installed in my Amiga. It's a whole 286 PC on an Amiga Zorro card. I'm not sure how it would fit into everything (it's totally independent from the Amiga, communicating through dual-port RAM and some special BIOS functions, I have the developer manual) but I was able to locate dumps of all the onboard ROMs online. It doesn't boot just putting the BIOS into at.cpp but I didn't expect it to.

OS/2: there is a 1024 cylinder limit, which means you cannot work with hard disks beyond 504 MB.

1024 cylinders, 16 heads and 63 sectors.

See thread
