The bulk caps withstand much less stress than the others. If you have an SCR meter, you can pull and test them, but I doubt they'll need replacement.

If you want this to be retro remove this thing and go right for Pentium I or AMD K6-II, or even 486... Pentium IV is many things but not retro. Instead you can try to make Pentium IV ultra build with all parts maxed, instead of this mid range... I'm sorry, I must have missed the meeting where that …

Yes, ideally you'd need a CM-32L/LAPC-I and an MT-32. Munt gives you both.

Different layers, or possibly with a metal link, just as you'd expect. Building wiring trays for something that small would be a bit of a challenge, I think.

Would all (or most of) the lines be parallel with no or few exchanges in orientation? If so, spinning a small double sided board might be inexpensive and straightforward. The random orientations of jumper wire probably generate a lot of cross talk. Proper perpendicular crossing (when necessary) …

Of course Ultima 6 is pre-General MIDI, but isn't the only major difference between the MT-32 and GM that the instrument assignments can be a bit different Partially correct. MT-32 or compatible devices can also be programmed with custom instrument sets via SYSEX messages which is something some …

There's a handful of games which only sound right with the glitches in original MT-32s. I understand the revised version (with the dedicated headphone jack) is kind-of the worst of both worlds wrt compatibility, as it's not the best for those titles which use glitches, and it doesn't support …
