I've been having fun today with getting my Soundblaster 2.0 knock-off to have CMS sound. It works with the same CMS GAL as described here, pinouts are all the same 😀
The first GAL16v8 I bought was a used one, which was a mistake because pin 3 on that chip didn't work, which lead to patchy / single channel CMS audio. The fresh GAL16v8D came in a couple of days ago, .jed file made and flashed onto the GAL.
After that, just remove the CMS jumper, install the chips and it works. I've only tried it in KQ1 so far, but it sounded good with really nice stereo effects.
With that, I had a good reason to test out this PCA-6134P SBC I bought last week. A cacheless AM386 SX-40 made in around '96 that takes 72-pin SIMMs for memory. It even has LBA support in the BIOS 😀 To start with when I plugged it in, it seemed to be cutting out, that that was just because I'd set the bench PSU current too low and it was detecting a brown-out and shutting down. The CMOS battery on the dallas chip block is dead but the board appears to be working otherwise.
This little PC has it all, motherboard, CPU, DC-DC PSU, IDE, floppy, parallel/serial then graphics and soundcard in this fairly tiny space of 190 x 150 x 80 mm
