well if you have 00 + 01 the difference is really obvious if you looked at the pcb. but neither is 'better', they both have quirks. take your pick. 00 is ceramic pga. roms as eeproms 01 is plastic qfp. roms are mask roms. Yes the physical differences are obvious. By 'better' I meant which one …

Here are the firmware version notes I found at https://en.wikipedia.org/wiki/User:Lord_Nightmare 1.04 - unknown, initial release? 1.05 - Volume knob changes are now interpolated as opposed to directly applied to the data, allowing for much smoother volume changes when using the knob 1.06 - Rhythm …

the joystick plugged into the adapter on the MT-32 midi gameport cable does not work (though the MT-32 continues to work). What joystick are you using? Some joysticks use the MIDI in and out ports as supplemental I/O. That means they will not work through a MIDI/Joystick adapter cable. For instance …

I'm in the same situation as the original poster. I have two MT-32's. Both "old" versions. But different motherboard revisions (79377310 00 vs 79377310 01). Are there any known differences between the two motherboard revisions? Which one is "better"?

In case anybody is curious, the correct EPROM ICs are 27c256. Two are required for IC26 & IC27. I wont link to the ROM images as I think it is against vogons rules. But they are out there.

Not the answer to your question, but you can buy a pre-programmed ROM set on one the usual marketplaces. Yes I've seen that. But I don't like paying someone else for something I can do myself. I have a couple EPROM burners. So I'm confidant I can do it all myself, if I had the files and the right …

I have a Roland MT-32 with firmware 1.05 that I'd like to upgrade to firmware 1.07. Which EPROMs should I used? Where can I download the .rom files? I thought this info would be easy to find, but my google-fu is failing me right now.

I'd be glad to help test your card. I don't speak Russian. But I have my own tools including oscilloscope, meters, power supplies, soldering iron, hot air station, etc.

Please don't waste time/effort/money designing and producing boxes. Suppose you just bought a lamborghini and it's towed to you like it is a 96 honda civic. I'm pretty sure you will not be very pleased. This card ain't going to be just another cheap noname clone you can pick it off ebay. Trust me. …

No, the nail in the coffin was storage space of CD-ROMs. The whole point of using MIDI was to allow orchestral soundtracks even for games that came on floppy. With CDDA or otherwise streamed pcm/wave music from a CD, MIDI no longer had advantages - especially considering that not everyone had MIDI …
