1) Does SoftMPU have a minimum CPU and/or RAM requirement?
2) I've seen videos on youtube showing SoftMPU outputting MIDI to an MT-32 through the serial port. Does that require a sound card or could you do that on say a 5150 with no sound card (stipulating that SoftMPU works on an 8088.)?
I wonder, how did anyone connect an MT-32 to their PC? I had, and still have, an MT-32, but it never occurred to me anyone thought of it as a PC accessory. I used it with all the rest of my MIDI stuff, which at one point included an XT, but I never used it the way most people did, apparently. I just used it as a really lousy-sounding MIDI synth.
