Excellent. Does it work? (don't worry, this is the question I ask of everything I build myself too 😀)

Yup the "QC passed" sticker chip is an OPL3 or a clone of it... the DAC is the chip directly to the right of it. CT2501 don't have OPL3 or CQM inside, any FM synthesis needs to be done by external chips.

There's a wide range of values between 7.5k and 100k. I have ordered a bunch of precision resistors and will do some testing with various values when they get here. Which may be a while.

Yeah, it's clearly not a problem with LBA support since you mentioned the same board is working fine with HDDs and even CF cards > 500MB. I know you said that currently you don't have another PC to connect these DOMs, but maybe if you have one of those IDE --> USB adapters you can plug them into a …

Since the physical and logical geometry has 16 heads and 63 sectors, I don't understand why creating a 500MB partition does not work. It does work. I can create a 504MB partition, format it and transfer the system to it. After reboot, all the files are there. But the system doesn't want to boot …

I can't find that one. I found some mention of it on a few "driver update" sites that only try and make me download their "driver fixer" utilities instead. Here: http://www.filewatcher.com/b/ftp/ftp.aopen.com/pub/bios/vi15g-0.html vi15gr23.exe is a self-extracting file with the 64K .rom inside. If …

The exact same thing happens as with the first DOM after fdisk/mbr, reboot etc. Size seen by DOS fdisk is 504MB. But does it boot now? No. And are you sure that you didn't partition and format, the drives that show larger capacities, in another computer or using a different method? I personally …
Re: My Wavetable Sample Thread

Nope, tried X-wing both in pure DOS and under Win3.11 and I get no GM music. I can only get sound if I select SB (and that required some juggling of drivers, to meet the minimum memory requirements of the game which is 550K - I have many drivers including PCMCIA and Mwave DOS drivers).
Re: My Wavetable Sample Thread
Posted on 2017-01-13, 17:38
Unfortunately it doesn't look like the Mwave drivers emulate a MPU-401 compatible device under DOS. I can't get any music in games that allow selection of GM or MPU-401 (tested with: Doom, X-COM, Frontier First Encounters). The latter has an extensive setup program with many options for sound setup …

Well I'm not really planning on using the ISA card anyway. I was going to use the laptop card assuming it does allow MIDI music in games.

Through the USB you can access directly the MPU and its memory. The waveblaster connector doesn't have a channel for communication with the MPU directly. It only conveys MIDI data and audio signals.

Problems with DOMs
Posted on 2017-01-13, 02:25
So I got myself 2 industrial DOMs to see how well they would work in my retro systems. One 4GB and one 8GB. The only system that I have out of the box right now is a 486 that I was working on a little while ago. So I plugged them in one by one, and here's what happens. The BIOS autodetects them with …

Good luck with that. CPU-World members don't seem to care much about having working hardware. I do. I only buy working chips (or at least ones for which I have a reasonable expectation to work). For me it's not about keeping them on a shelf in a display case, but using them. At least for x86 …
