Retro Computer Repair : Abit VH6T Mainboard

Retro computer repair : Abit VH6T mainboard

A few months ago I started to build a retro computer out of broken parts from the junkyard and extremely cheap stuff off the internet. Playing games like I used to back when I was a kid (Duke Nukem 3D in a real DOS environment or Archimedean Dynasty with a physical 3Dfx card) is absolutely amazing. I also need to use the GamePort for my old joystick but that connector hasn’t been supported since Windows 7 anymore.

So I got hold of the Abit VH6T mainboard. This is a very special kind of hardware. It still comes with the old ISA slot for adding a Soundblaster card, supports up to 1.5GB SDRAM and it can even overclock directly from within the BIOS. The best feature of this motherboard is the support for 1.4GHZ Pentium III (Tualatin) processors, though. DOS gaming on a 1.4GHz machine? Hell yeah, baby!

I received this mainboard in a broken state for one buck and refrained from turning it on immediately. All of the capacitors on this board are broken and they must be replaced in order to use this board in a stable manner. Because of this reason, there was even a class-action lawsuit against Abit in 2005 and the company was ordered to give the customers their money back or repair the board without any additional cost.

This obviously doesn’t help me much –  14 years after the fact. So I started to comb over the board from top to bottom and noted all of the values for the capacitors and their respective positions. An overview of this result with all suitable replacement parts is available here:

Color/PositionValueQuantityReplacement
BLUE2200uF@10V12EEUFR1A222L
GREEN1500uF@6.3V7EEUFR0J152L
RED1000uF@6.3V5ULR1000/6.3L
PINK220uF@16V3EEUFR1C221
YELLOW3300uF@6.3V1EEUFR0J332L
NEXT TO BIOS CHIP100uF@16V1EEUFR1C101
ALL OTHERS10uF@25V22UVZ1E100MDD

I was able to order all of the replacement caps relatively cheap at Darisus GmbH. Only the 1000uF caps were problematic – I wasn’t able to find a suitable replacement so I used entirely different polymer caps. These are a bit on the expensive side but they will live much longer.

After replacing all of the components the machine is now working perfectly fine. Time to play a game!
