They already exist.... but most of them are in USB format. In fact they've existed for a good 15 years or more, these days they're down in the size of a thumb drive and work almost identical to a Gotek or similar. I've not seen any native IDE/SCSI connected devices.

Depends if the mx400 has a DVI-A, DVI-I or DVI-D connector. DVI-A is analogue only DVI-I carries analogue and digital (and will work to HDMI) DVI-D carries digital only (and will work to HDMI) https://en.wikipedia.org/wiki/Digital_Visual_ … ector_Types.svg

It really does need to be made clear somewhere that you cannot play the DOS version in English in DOS, only using the SDLPal binary within Windows. It needs a matrix of versions and platform binaries to show what is possible, because frankly, it's about as clear as mud! 😁

The question is x86/Windows or just "the best damn workstation possible in 1996" ? If the latter, then you're talking: - Sun Ultra 2 - SGI Indigo2 - SGI Onyx2 deskside (just scrapes in, being introduced in 1996 as a side-by-side replacement to the original Onyx) By a long way the Onyx2 would have …

I must be in the minority - for a large chunk of my career I looked after server infrastructure (Dell, HP, Compaq, Sun) ; unless it's something really special (and almost none of the usual x86 stuff falls in to that category) it just doesn't do anything for me. Too big, too power hungry and too …

The SC55 doesn't require sysex programming in order to set it up for each game. Most MT-32 games do, otherwise they either won't sound right or work at all. You can "emulate" this if you have a real MT-32 in a chain after another device; start playing a midi file with the first device turned on, …

I settled on the use of the VLSI 82C200 board in the end - couldn't get the Biostar to work, even reflowing the main chipset IC. The VLSI has been running happily at 20MHz, 0-wait, since I was never happy about the instability at 25MHz. I've since bought a set of 40ns rated, newly produced simms …

Yes, the Cyrix 5x86 is much more competitive on an integer performance basis - look at the 3DBench and Doom performance metrics; they're much more inline with the Overdrive processors. At the time Intel had put a huge amount of development into improving the FPU architecture, although it wasn't …

Does it freeze when you do a copy from the hard drive to somewhere else on the hard drive? i.e. exclude any other drives. Another thing I would be checking is memory; it's often the cause of random freezes and glitches - give memtest86 a run and see if you have any errors show up.

What's the resistance? Perhaps one adapter has slightly higher resistance than the other, causing the keyboard signals to be out of spec for the KVM?
