QDOS does a damn good implementation of glquake, and runs in pure DOS with a 3dfx to boot

Nice system. I don't see a keyboard or mouse port anywhere... does it have PS/2 mouse support?

If you can get the memory total up to 512MB I'd heartily recommend XP SP3, that's what I run on my PPro dually. But 256MB is a bit anemic for XP

The OP never specified a drive model, but I compared the motor PCB described here to my Alps DFL413C02B from my IBM 4865 External 3.5" drive and it's an exact match. My drive apparently has a perfectly working motor PCB, just tested and I'm getting a 5Hz signal from the index wire (blue) but I am …
Re: Do Tualatin core CPUs burn out without a heatsink on?

Is there any reason you don't want to use a heatsink and test them safely? As I understand, the OP is not worried about overheating processors now, but is worried about "untested" processors that might already be destroyed due to use without a heat sink before he or she buys them. The question is …

For future reference the program ImageDisk contains a built in RPM test function. Great work reversing the motor PCB btw!

Mike is probably going to refer you to his documentation, which contains an overview of the TZ variable in the SNTP section, as well as a link to another PDF with the full syntax

The ISA bus can only address (the lower) 16MB of memory. Would be a bit pointless to make an ISA expansion card that supports 4MB sticks The ISA bus is 16 bits wide, so 2 sticks form a bank. 2*4MB = 8MB on an ISA memory card might make sense. I suppose you're right looking at it from a modern …

the baud rate on a standard (logitech notwithstanding) serial mouse is so garbage you might not even notice it was optical

In windows the compatibility is perfect. In DOS it all comes down to your BIOS' implementation of USB legacy support

I'm sorry if my post came off as entitled or ungrateful. I understand there is still a valid use case for these things, I just would love to see someone write some software for one that would realise its full potential

Desoldering the broken socket would be easy. You could replace it with a regular LIF socket, they might still be available new

I like a bit of blur better, it more closely resembles the real budget CRT that I have (and I had with my 486). They never were sharp, also not in Windows if you went above 60 Hz to prevent headaches. Only when I got a good weekend job I could afford a proper CRT and after that I went with LCD and …
