Replace the A2000 PSU With an ATX
I was sent an Amiga 2000. The powersupply on it died.
So how to fix this? well. you can put in an modern ATX Powersupply. So I did, and this is a short writeup of how to do it.
First of all, as most (all?) modern ATX PSUs do not contain the -5V signal, you will have problems using some ISA cards if you use a bridgeboard. but as this is not a very common usage, this will not be a big problem.
So, first, remove your old PSU and open it.
IMPORTANT! do NOT touch the big capacitors on the A2000 PSU or the ATX one.
