PDP 11/34 Settings

Tarsi,

I do have a working 11/34A, so first, we need to make sure we have the
same pair of processor boards (one board is "control", the other "data
path"). I am not currently at home, but IIRC, the older 11/34 has boards
labelled something like M725x, while the later 34A has M825x boards,
with x being two consecutive digits for both boards in a pair.

Whatever boards you have, once we know the M numbers, I should be able
to look up the desired info from some piles of documentation.

It may also depend on the boot ROM board. There is probably either a
M9301 or a M9312 board in your backplane near the processor, and there
may be additional jumpers on these boards that need to match your
configuration, such as termination for certain bus lines.

In addition, there need to be boot PROMs matching your boot device and
controller.

So, please let me know precisely which boards are involved, and I'll
certainly find the information you need.

Regards,
Andreas
