Haven't messed with the PDP-11 in a while (been saving cash for other stuff), but I did get my hands on a M9301-YF, since the M9302 I got had the wrong ROM. From what I read, the /04, /34 cpus have pull up resisters and W1-W5 do not need to be jumpered right? I set the dip switch to ON,OFF, and all the rest ON. My system looks like this:
M7263 M7263 M7263 M7263 M7263 M7263
M7891 M7891 M7891 M7891 M7891 M7891
M9301 M9301 M7856 M7856 M7856 M7856
EMPTY EMPTY M7856 M7856 M7856 M7856
EMPTY EMPTY EMPTY GRANT EMPTY EMPTY
EMPTY EMPTY EMPTY GRANT EMPTY EMPTY
EMPTY EMPTY EMPTY GRANT EMPTY EMPTY
EMPTY EMPTY EMPTY GRANT EMPTY EMPTY
M9302 M9302 EMPTY GRANT EMPTY EMPTY
The memory's power led is green, and the parity error light is off. Now, I only have an operator's panel on this so it really makes it more difficult to debug the machine. If I flip the right switch to HALT, would it shut off the RUN light? Also, are there any guides on making a serial cable for the M7856?
