In my hunt for a Model 2, I managed to buy 2 other computers, so today I collected this diskless 48k TRS-80 Model 3, sold with a suspected PSU and Keyboard fault.

I think the computer case and keyboard cosmetics are in great condition, the insides also look very clean.

It came with no screws holding the top to the bottom so need to work out what size of screws to use, if someone can tell me that would be great.

It was soon obvious that the Astec PSU had reached the end of it's MTBF - luckily the board looks in great condition, so resurrecting this should be quite easy.

I didn have any of the higher voltage capacitors in stock, and had to order 5 of each, so ended up spending 1/4 of the price I paid for the whole computer just on fixing the PSU..... ho hum
