Anyone got a Pet 2001 with a really good picture of a working motherboard
(so I can verify the chips are all in their correct sockets, aligned the
right way, etc?).
look near the sockets very closely. Near each socket, a number is
printed in the copper layer, showing where pin 1 is for most chips, and
sometimes showing e.g. pin 40.
