Hi,

I just bought a pdp 8/m and I'm trying to get it working.
When I got it home I discovered that someone had put the
M8330 timing generator module in backwards and, it looks
like they then powered it up.  This fried one 7401 chip.
I'm going to replace it, but I assume other chips will
be bad too.

So, to find the rest of the bad chips I probably will need
a schematic for this board, and maybe others.  Does anyone
out there know where I can get a copy of the schematic (for
the M8330 or better yet the whole machine)?

Has anyone had any experience with what putting a board in
backwards can do to the rest of the machine?

Thanks,
Paul
