I have Unisound configuring dual sounds cards on my 486 under DOS. I have an SB16 Vibra and YMF719-B. The SB is the main card with a short audio cable from the YMF's unamped out to the SB's line in. The SB handles digital audio and game port, the YMF handles OPL and external MIDI. It's possible to …

I am interested in the Compaq 003560-001 256KB cache module. I have some other 486 computer with empty COAST slot that is physically same, would love to test if it works. What 486 motherboards do you have? The PC Chips (and other rebrands) M919 boards have what looks like a COAST slot but it's its …

One thing I haven't seen though it's possible I skipped over it, is what level of performance level are you shooting for? You say outside of the XT speed sensitivity isn't a major issue, but there are games that require slow or fast 386 speeds, 486 at 33Mhz, as well as 66Mhz for a better experience. …

PSU should be fine. No, but it can make things much easier. I recommend a Gotek Floppy Emulator rather than a real floppy drive. It lets you put floppy images on a USB drive and is seen as a real floppy drive. They are under $20 USD. Win98 can use SATA, but some chipsets work others won't be …

I haven't used that motherboard so I can't comment. But it does have a VIA chipset so it should work with pure DOS mode sound. Other chipsets like the NForce can't do pure DOS mode sound with most PCI sound cards. I ran GLIDE Tombraider just fine on my Win98 machine with dgVoodoo. You just run it …

What about using a SD2IDE adapter to replace the hard drive? SD cards are faster than old HDDs, and you can mount it so the SD card can ejected to transfer files without needing to open the case.

Are you set on running games in our pure DOS mode? If not get a 4200ti or 5500FX and use dgVoodoo for glide games. SB Live or SB Audigy for sound. SD2IDE to storage and you have a great 98 era PC.

I would certainly fancy a more self-contained version of this device. Do you have any news about that DOS utility, so we can switch CD images from inside the host machine? Usage it in a retro gaming rig would be far more viable, if I didn't have to connect the IDE simulator to another computer. …

I received the cache stick today after it was bouncing around in the limbo that is USPS these days. I put it in my M919 V3.4b /w AMD 5x86 @133Mhz and it passed cachechk and topbench without issue. The listing states it was tested at 160Mhz by the seller. Phil's Quake benchmark saw the ~20% speed …

You're going to need what model motherboard that is or a much better picture to help people identify it. It looks like a DX2 chip is already installed. What voltage is that chip? If it's 3V you might be able to get a regular DX4 100 as overdrives expected 5V and then have voltage regulators to drop …

There you will fall back into the problem mentioned in your first question. I don't believe you understand my first question. With two RPi 4 CMs on a single waveblaster header.

Is it a good idea or not? the waveblaster header has a Midi out pin (wavetable board to sound card). this pin is rarely used on wavetable boards (one card to my knowledge). Is it possible to transform this pin into midi IN in the WP32 McCake module and thus have a total of two midi INs? This would …

The SC D70 is based on the 8820 so it's not a direct replacement of the 8850. But the SC D70 has both optical and digital via USB audio output that's mixed at a higher frequency than the 8850. So while things won't sound 100% the same, the SC D70 can give a higher quality ound. I'd recommend keeping …
