Part two of the repair of a Commodore Amiga 2000 motherboard. The corrosion was dealt with in the 1st part, in this part I identify a couple of RAM faults, make up a keyboard adapter (A500 Keyboard), carry out some required factory mods, add a CR-2032 battery for the Real Time Clock, and test a few things out.

A short video covering the repair of the modulator in a Commodore C64 computer. This system was working OK but the display was a little blurry. On an LCD TV it looks almost like it would on a CRT.

A short follow up video to a video I did ages ago on my Sega Mega CD. I litterally bodged some caps on there back when I first fixed this unit and recapping it properly has been on my 'to do list' for ages.
