Then I saw this message which is... concerning. I think some admin was perhaps a little overzealous. An actually sensitive computer wouldn't have been sent to an ewaste facility with its drives still intact. Filename IMG_9963.jpeg File size 1.61 MiB Views 179 views

Success! I tried to boot the computer with only a single RAM stick in the second DIMM slot and the computer booted up! Something seems wrong with the first DIMM slot

Reseated everything and booted with just a IDE CD-ROM and I got the computer to boot into memtest86! It looks like there is some memory error but I tested all 4 sticks in another computer and they passed all tests. This points to the motherboard being the issue. The errors are still counting up but …

I'll setup memetest on another (working) computer and test the ram, but I did already try the ram in that separate computer and it worked so I think if it is a memory issue then it's an issue with the memory socket on the duel processor MB. If the memory tests fine what are my options? Is this …

I picked up an old PC with a Tyan Tiger 133 motherboard that is a duel slot 1 MB with 2 Pentium 3 800EB processors and 4 sticks of 256 MB PC100 RAM. It also had some other card but I've been trying to bring the computer up and running but so far the furthest I have gotten is to the point where is …

I have an AT keyboard that I plugged into an IBM XT (I wasn't thinking), now when I plug it into an AT computer it no longer works. Anyone have any ideas what to possibly test on the keyboard PCB or what part is likely to have fried?

I have watched what I think is every Voodoo 2 video on YT and I have yet to find a video of the kind of issue I'm having. The Voodoo 2 doesn't appear to have any obvious signs of damage and mojo and the drivers both start up successfully. However most 3DFX apps crash when run (like any of the test …

I finally figured it out. I tried removing as many variables as possible, and in the end, it had nothing to do with the XT-IDE or even the various adapters. The partition on the SD cards and on the CF Cards all lacked a Master Boot Record (even when I deleted and recreated the portion tables). In …
