Thanks, zapbuzz, I will look into that. I decided to test and brute-install DOS 7.1 on this board using an 80GB Seagate hard drive, and I got some surprising results. When looking in the BIOS, I can indeed see that the limit is 8GB , or slightly over with the latest P10 BIOS but when I installed DOS …

Your worries are wise. Use an opto-coupler/opto-insulator on the reception side (Pi+MT-32 hat). There already is one on the pi hat and as I understand it, you don't put those on the outputs, only inputs. I also checked the schematic of my JV-1080 and it too has an opto-coupler on the MIDI IN as I …

Looking for the simplest way to connect a Sound Blaster to a Raspberry pi with a MT-32 hat . What I understand is there are basically two ways, 1) use a buffer and two resistors and 2) just use resistors and skip the buffer entirely. So just to confirm everything is okay, this schematic is correct, …

Thought I'd be smart and install DOS 7.1 to get support for larger partitions, alas, I soon discovered that my Intel socket 7, MMX 200, LT430TX board doesn't support drives over 8GB. So what's the best workaround for this: Look for a BIOS hack Get a PCI IDE card and use SD to IDE Get a PCI SATA card …

Ah, now I understand. You want to know if AWEUTIL provides an intelligent MPU-401, as in MT-32 emulation, but for the physical MIDI connector? Yes, exactly. Or if SoftMPU would work just like on a normal SB16 so I can hook it up to a real MT-32 or a SC-55 or anything connected to the gameport/MIDI …

kolderman wrote on 2022-11-08, 06:36: If you are using external midi you dont need to worry about emulating midi, just ensure passthrough is enabled. And yes you always need aweutil for it to work at all. Got it. What and where is 'passthrough' though?

I'm about to pull the trigger on a AWE64 Value but one thing is rather confusing about AWEUTIL - can I use my MT-32/General Midi with an AWE64? I get the impression that you have to use AWEUTIL to get music at all and that you have to use the 'emulator' function which, somehow gets you MT-32 sound …

dr.zeissler wrote on 2022-10-20, 13:35: - you can use MT32 or SC55 with these AGI games (when patched) I prefer SC55 which sounds better. Is there a guide to make this work and is using the MT32pi going to work for this?

Thanks for all the answers and suggestions, it would seem that I need a PCI card to get most out of the Doom games, and I say that because now I have tested some other games. Rise of the Triad runs almost as bad as Doom 2, about the same as Doom but Heretic runs absolutely flawlessly, no stuttering …

Your system is likely too bottlenecked by the ISA graphics card already. I get that it's bottlenecked for what the computer can ultimately do. But why is it slower than a 486 33SX playing Doom 2? I didn't have a PCI card in my 486 in '94, it was a Cirrus Logic 542X something-ISA and I didn't get …

Also, looking at that Speedsys screenshot, you seem to have 128MB RAM installed. This could also contribute to the slowdown since the Intel 430TX chipset can only cache 64MB. Uncached RAM is much slower and can reduce overall system performance. I think I have a 32MB laying around, I'll test that …

Trident TVGA9000i this is your fault! Get any PCI card, like any generic S3 Trio64 for 5€ it will be miles better ;) The reason I got the Trident card is that I wanted to try out the VGATV since my only VGA CRT is a rather shitty 17" to instead run it on my Sony 21" CRT TV via SCART RGB. There's a …

Finally got around to test my Pentium MMX 200 out and was absolutely floored when I saw how poor the performance of Doom 2 was. With only a graphics card installed on a new 6.22, no other software, no TSR's, no mouse, no sound, nothing other than a raw, basic system, I get maybe 10-15 FPS . Granted, …
