Honestly surprised it runs this good. Perfectly playable. https://www.youtube.com/watch?v=KbcFvUOGA44&t=14s Except for the sound. The poor sound card can't keep up at all. This. Our expectations were lower. Most of us probably ran Doom at 20fps, and it was revolutionary. Now if my games run at < …

Not playable it seems to many of your standards, but 25 years ago that was all I had and I wasn't going to let anything like borderline negative fps get in the way of me playing a game 8) Doom is another one that I remember running much faster, but I think I've proven that my memories of such events …

Quake responsive and playable at 4fps on a 486DX-33? At what resolution are you playing Duke Nukem 3D? Anything above 320x240 will be stuttering on all low to mid range 486 PC's. Minimum requirements for Duke Nukem 3D is a 486DX2-66. Dont expect stellar performance on a 486DX-33. It's perfectly …

My memory must be playing funny buggers with me because I don't remember my old 486 running certain games as slowly as my new machine does. Most 2D games it runs really well (almost like they were made for it) with some others being playable but not the greatest like Quake. Quake runs at about 4 fps …

I've been looking for a better keyboard than the one I currently have on my 486 where the space bar flops around like dogs ears and the enter gets jammed down after pressing it. It's a real junk heap. I found someone selling an HP C1405A that looks to be in great condition, but it doesn't have the …

Both OnTrack and EZ-Drive were giving me inconsistent drive information with the three CF cards I tested and BIOS was also acting strange when detecting two of them so I'm guessing the adaptor is dodgy. That still doesn't explain what happened with the hard drive that was in it and working perfectly …

I loaded OnTrack to split the 4GB card into two 2GB drives, loaded DOS and everything else I would for my …

I've noticed recently with my 486 using a Microsoft Serial Mouse (pictured) that horizontal scrolling isn't smooth like vertical, it seems to jump or stutter and in lower resolution games it looks like it skips a pixel. I'm wondering if this is a hardware issue with the mouse or possibly the LCD …

is it just the CD-ROM issue you were left with? I'd plug it into the second IDE port as master. The CD-ROM and the weird installation error I kept getting trying to install the sound card drivers. For all I know it could have had errors installing other things like games, but I never took it that …

That's a 2000s era Gateway mouse. It's definitely PS/2 only. Those microsoft mice usually say on the sticker underneath if it supports serial and ps/2.

Are you referring to the smaller connector that is used on floppy drives? If so, there are adapters that take the bigger molex connectors down to that connector. If you've ever bought a new power supply that has removable cables, they almost always include some in with the cables. Yes that's it. …
