Back when I started this hobby I was quite enthusiastic and I got my hands literally dirty with everything.. I'm usually a scrapyard buyer, I get things that got neglected in storages, garages and attics, when they are sold by people who just want them gone for cheap. I've found out that these …

On my board the keyboard controller was defective (among other problems). On yours, I see what looks like corrosion on two vias near the KBC (above R43 / D2). Check to see if you have continuity between KBC pins 1 and 39 and the data/clock pins on the keyboard connector. I will do this tonight, …

When in doubt, go for a thorough cleaning and repaste.

I had a Philips Brilliance 107P4 which could do 1920x1440@60Hz but using that resolution was incredibly impractical and I never had the graphics hardware that had horsepower for that (neither do I think there ever was such hardware for that). 1280x960 was my desktop and gaming resolutions of choice …

Got these printed because it seems I will be needing them for my many upcoming sound card soldering projects.. I will be drilling holes for my Adlib using Dremel. Anyone know exactly what size nuts and bolts I need for these?

With Turbo header closed it takes roughly 1 minute to complete memory test and report CMOS and keyboard errors so that is twice as fast as before but still terribly slow.. Hopefully it will be better once I can get into BIOS and save some CMOS settings..

L2 cache is not on the CPU and in many Socket 7 boards cache amount can only be set by jumpers not through BIOS or other CPU registers. In these cases the L2 cache switches are useless. If you use a CPU with onboard L2 cache such as the K6-22+ on these boards the L2 commands will disable the L2 …

There is only one thing that matters.. Can it decode x265 in hardware? Otherwise it's worthless to me. EDIT: YES, it has H265 hardware decoding; I'll eventually get one to replace my media player setup.

Any ideas why it might be booting SoooOOoOoOoOOoooo SlooOOoOooOOooowww.w.....? You need to get into the CMOS setup. Chances are that your system boot up speed is set to "normal" and not "fast". At the same time, check your turbo header on your motherboard, make sure it's connected and that your …

Ok, it's ALIVE! Not completely, but it's alive nonetheless. Video of the POST process: https://youtu.be/cebsE0l83M4 Video of the Debug Card: https://youtu.be/-uiw0GQ-JUo So basically it boots and POSTs painfully slowly for whatever reason and ends up with a keyboard error and no lights on the …

ISA in 1993 sounds fairly outdated to me.. I got my DX33 in 1992 and even then I was advised to not go for ISA as it was a deadend, and got a VLB system instead. That DX33 with a VLB Cirrus Logic was my first taste of Doom.

Just an observation. In the pictures you posted, I noticed that you only populated the two simm banks that are the furthest away from the edge of the board. Is bank 0, bank 1, etc. clearly labelled on your board? Isn't bank 0 perhaps located on the outer edge of the board, since some motherboards …
