There is a raspberry pi running kermit with a DigiKey usb->RS232 adapter attached. The 486 runs CKermit. The Raspberry Pi hits a restful endpoint, grabs the midi file, sends it via kermit to a ram drive on the dos machine, and sends commands over kermit to run dos programs to play the midi file. I …

I forgot to mention: the FCC ID is listed in the back end of the machine, or underneath. Also, what is the BIOS version? Is it 1.01 Ref ID xx? The machine is busy now running that website, so I don't really want to mess with it right now. If\when it crashes, I'll check again, but I just bolted the …

....and the soundcard is a Yamaha YMF719-s OPL3. Not exactly sure what it is, the closest I can find is an Audician 32. The model "ATC-6631" indicates that it's manufatured by Atrend. Here's hoping the Audician drivers work :D Yup, it will. OPL3SAX, SETUPSA will make the card work dandy. Literally …

Glad you got it sorted. Were you still unable to boot from a floppy? Correct. If I try to boot from a floppy it hangs. If I put in a controller card for it and disable the onboard it hangs. If I disable the controller and try to boot from a hd it hangs. I have to leave the floppy controller enabled …

Little bit of corrosion where the bios battery was. Wondering if this is why the floppy conttoller is no good? I can’t disable the floppy controller, it won’t boot off the hd if I do that.

So, I got it. The bios is just trashy. The floppy controller is outright toast. Turning off the controllers in bios and using a controller card doesn’t work. I installed a software bios helper, EzDrive, which takes over 13h functions. This works. Boots 6.22, Freedos, and 98 now, on a 4gb cf and …

I think it's a 430 or 440 motherboard. The model of the computer is a BL120CD Not sure where the FCC ID is. Maybe it has a hardware issue. I am trying multiple CF cards, none of them will boot, off the EIDE controller card or off the onboard controller. CHS settings are detecting properly, same as …

I have an old packard bell. It’s a 486, somewhere I have a digital copy of the manual and the model. The floppy controller I’m pretty sure is dead. What has been frustrating is that even with one of those SIIG eide controller cards with the helper bios, it hangs before trying to boot from floppy The …

That is also true here - pretty strange, the soundblasters I have are all pretty quiet. It's working well in the other PC I have now, thanks!

I did get a Yamaha YMF719 based card in, it is playing ad-lib tracker files finally now without getting garbled. Having some audio quality issues with the card - it's a "Soundmax" 3d sound card. It's getting better - tweaking the drivers, turning off 3d sound, setting the jumpers to line out instead …

I gotta say, this has been an uphill battle! I had the thing stable finally for a bit over 24 hours, trying different software to play back midis. Confident that the planets were finally aligned right, switched it to a different 486 with an old 3Com Etherlink III card instead of the Xirlink PE3. Put …

Curiously, everything works fine in Win98 without the I/O recovery setting(that can't be used in the standalone player), on the 486. The IRQ moves to 10/11 via Windows plug-n-play away from 5, not sure if that is related to anything. Nothing conflicts with 5. I could move the site to the P1 233... …

Thanks. Found one for 10 bucks on eBay! Here we go again...gathering quite a collection of old sound cards! Also went rummaging in the basement, and found a P1 233MMX comp. Same problem on that so it's definitely just that all of my sound cards don't work with Ad-lib Tracker without that OPL latency …

I got the card in. It's still happening, even worse. This is in an entirely different 486. So I have 4 sound cards that don't actually work, SB Vibra 16, a real SB 16, and two Aztech Sound Galaxy Washington 16 cards. They're working for everything else. And also work in the tracker with OPL_LATENCY …

Ok - the OPL_LATENCY setting DOES work - but only for the tracker program, not the player :( Also, I edited the queueing so it pulls from the top and bottom now - less waiting. Edit: Argh! I give up, ordering a CT2290, which is more soundblaster-y than a Creative Vibra 16 or an Aztech Sound Galaxy …

Yes- both versions tried. .53 and .52. My goal actually is to move this to a different 486. I want this one back for games ;) I have an old Packard Bell with a busted floppy controller. Once I get that up, I can try on there too. Edit: And the other player seems to work once. Most .A2M files it says …
