Reviving this thread, I have the same 4DPS tomatoboard, although a socket 3 with a mouse pin header. I've tried flipping 1 and 2 to no avail. Can someone verify my assumption that pin 1 on the board is the one thats black in the user manual (closest to the keyboard port) https://theretroweb.com/ …

Little update, both my Beeper and POST board arrived. The beeper gives a continuous stream of beeps, and the POST board says C6C1 which seems to mean an external cache error. From my read of the manual it seems like the board requires all 4 cache slots + Tag RAM to be filled, so I suspect I'll need …

I dont have a beeper on hand, but will order one. No LEDs or anything on the board. Everything is a question mark including me :) I've reasonable confidence in the board due to the seller, and I've tested the PCI video card in another system. This is my only socket 3 board so the RAM / CPU were …

Thanks for the thought - yes the ATX->AT adapter has the 2 extra wires with a latching switch to turn on the PSU, i have a fan connected to it so I'm sure its on and putting out power.

It's been many years since I touched hardware this old so looking for some ideas from people with more knowledge than myself. The main board is quite late era with PCI and PS2 support, 4PDS 2.11 SiS 85C496 ZIDA which I got from an ebay seller as working and have bought many things from before. …

Oof... Yep that doesn't look good. Hopefully your future 1 GHz Athlon is doing better! Yup, the 1GHz effort is running great. I learned a few things along the way regarding using Compact Flash IDE adapters...turns out Windows 2000 is clever enough to detect its not a HDD and treats it essentially …

Thanks for the replies everyone, I think the first, simplest answer is probably the winner. How is the die of that CPU doing, any scuffs or pieces broken off the corners? I got so focussed on the pins and getting it nicely seated in the socket I didn't look too closely at the die...the results are …

Hi all, long time lurker, first time poster. Im recreating a build from my teens with an AMD Athlon 1400 in an ASUS nforce 2 motherboard, having done a bit of research I sourced a PSU with 480W rating and 35A available on the 5v line. The CPU had a rough journey to me with some bent pins, but there …
