[Coco] Fixing my "F" board TDP-100...

[Daniel Campos]

Pics or didn't happen! :-)
I'm also repairing a CP-400 now, the CPU was bad and has been changed, 
still doesn't boot. Changed all RAM and socketed VDG and SAM but both 
are good, now I need more sockets to change the PIAs. One of them I just 
slip the finger and the screen looses sync...
