@mattw, thank you for that pointer. I still have some JV2080 sound roms around that cannot be descrambled using the same available descrambling code as the SR-JV80 cards. That write up might turn out to be helpful. Though I also consider getting a cheap JV-1010 for the purpose of analyzing the sound …

So I have flashed and soldered a ST M29F800FB-55 with the rom and put WE to high. unisound sees it, but the md5sum mismtaches. play.exe does seem to play midi files, I'm assuming that it is using the rom. Is that normal and are there any other dos midi players that can make use of the rom file? I …

Yes, I have only been loading that ICU driver once nothing worked. There was no PNP initialization beforehand. The 486 doesn't have a PNP bios anyway. So I just switched my 486 with my Pentium-233Mhz MMX and this board could run pnpmap without any problems. After the cold start, the bios could see …

So I have finally built my Argus, but it's not detected by pnpmap on my 486 66mhz. I have installed the ICU dos driver from the discussion I have found here: https://www.vogons.org/viewtopic.php?p=643045, but pnpmap does not seem to like it. Do I have to try a different computer to program it or are …

A related question: did the software with which the RL2 demo songs were created ever get leaked, is the file format known or is it in any other way possible to somehow easily make use of the mixed OPL3/PCM functionality of the Adlib Gold/Golddlib card for new music in a retro machine when coming …

Thanks. For some of the ceramics I wasn’t really finding better than 10%, which seemed odd. I guess I’ll have to fiddle with my search parameters and try again. I'm curious about that as well. Mouser seems to be low on stock on some of the capacitors with low tolerances. So I went for the 10% as …

In the meantime, I finally had time to test my custom DIY front bay. It seems to work well 😀 Find it here in case you are interested: https://github.com/bzeiss/retro-pcbs/ By the way: for the cable, I ended up simply using a 20-pin IDC cable and connected only 9 pins of it.

It's actually true. I have tested a two-row right angled socket against the floppy connector and the floppy connector is still higher. So an unshrouded 2-row right angled pin header might not be as high as we thought.

How about a usb-c socket? Maybe misusing those pins for something else is something that works...it's reasonably flat.

Hm, true point. It's probably thick enough already for the next slot to be used. The problem is that many cables that are not IDC are likely again trouble to source or not long enough. The only idea I can come up with is possibly an FFC/FPC-10P connector on the WaveCake with a short flexcable that …

I think the improvements are very good. What I started to wonder when doing my custom floppy bay is whether the pins wouldn't be better in a 2x5 IDC connector layout. They'll possibly take slightly more space, but it's much easier to actually get those cables and they are pretty cheap. Plus having …

Unfortunately, I was too slow for the first batch 🙁 I have made a case anyway, I'm still iterating on it though... Edit: updated picture...I'm not to keen on the red though and probably print it again with a different color 😉

I'm curious though: it seems to be designed for use without a fan or heatsink. Won't that possibly cause thermal issues with the cm4?

Kinda weird for me. I've exclusively used Cubic player for multi-format mod playback in the 90s with GUS Classic and GUS Max and I remember it to be very solid back then (with versions lower than 2.0x though). I just went over the release log (https://www.cubic.org/player/geocities/mixer.html) …
