As for the topic: I've always enjoyed 8 bit guy videos and I still do. I wouldn't say he has lost his passion, especially when he's talking about the games he is programming. I guess sometimes you'll have to cover something you're less passionate about.. his income depends on it, so he doesn't have …

Maybe the inrush current on your variant is simply too high. How exactly is your rig wired up? You say you want to support AT style power switches -- i.e. switches that switch mains voltage, right? I would guess that ATX style PSUs limit the inrush current when switched on electronically. But you …

600 Ohms to ground sounds like a short to me. I think there is something wrong? I mean it's not terrible, it will do 5V/600Ohm=8.3mA only, and that itself shouldn't trigger anything. However I would have assumed that i see some kOhms to ground on 5V. But maybe I am wrong. How did you exactly measure …

Yeah, they were used in keyboards as well I guess. However I also think it's not viable to build many of these, as donors are probably quite rare still.

Howly cow. Thos LA32 Devboards look lovely! Amazing stuff! And yeah, I hope no MT32 had to be gutted for that! No functioning at least... I guess in the end an FPGA solution which doesn't need the LA32 IC would be best and give very good compatibility.

The Queen of Soundcards: Roland LAPC I The Roland MT-32 and its brethren CM-32 and CM64 were external MIDI synthesizers that were very much a gold standard for MS DOS gaming. There was one more obscure device though, which was compatible for the most part, namely the LAPC-I. It was a CM-32 and a MPU …

That's why you use MIDI THRU to send your keyboard to both the sequencer and the module at the same time. Unfortunately I'm limited by my input devices - an entry level Behringer keyboard and a Rock Band guitar, both with MIDI out ports only. Wouldn't the wiring be: MIDI Keyboard [MIDI Out] -> [ …

No worries. You're not dumb. I just wanted to make a snarky remark (pun intended). But good that you tested the contents. I just assumed it was the other firmware, but didn't bother to check.

How does a PC LPT detect ? does BIOS check for Status Registers to be present ? According to Sergey Kiselev's implementation the BIOS just writes a test value to the LPT and reads it back. If that is succesful, it assumes a printer port at that address. https://github.com/skiselev/8088_bios/blob/ …
