Hi all! I'm trying to launch Cryo Dune 1 on 386 machine with MPU-401AT and "old" Roland MT-32 (rom version 1.07) - and getting no music. Should it even work on this setup? (tried to start game from the same folder in Dosbox+Munt - and music plays - so it's not software-related)

Replaced R38 and got power led working. Still wondering what was the purpose of other missing components.

Horun wrote on 2022-05-01, 17:09: R38 appears to go to pin 1 of J13 so yes is probably for power LED. From the pictures it is a 150 ohm (brown-green-brown), cannot read the Tantalum C47. Wattage of R38 should be 0,25 watt or more?

Thanks everybody for your help! I see now that DX motherboards are indeed rare. Will look for 'classic' mbs that are available (will be assembling 486-era PC some time later, so additional versatility would be an overkill, but thanks for detailed explanation!) As for CPU/FPU, I have one restriction …
