As far as my PET, the only sign of life I can see is
the illumination of
an
LED on the board. In the interests of troubleshooting, I have removed the
z80 board and put the 6502 back in its socket. Does anyone have a PDF of
some type of service manual? It could be helpful.
I'm pretty sure google is your friend :) And with the service manual,
maybe you can get the composite video line that goes to the monitor and show
it up on a tv or external composite monitor :o)
