Acquired a PDP11/44, but missing M7095 - test-drb@ccmp.vtda.org

11 Dec 2002

The CPU has the 14 slot main backplane and a 9 slot expansion backplane, 
connected together with the M9202 jumper card pair.  When I first opened the 
top the M9202 jumper card was plugged into slots 12 and 14 of the main 
backplane.  I assume it is really supposed to plug into slot 14 of the main 
backplane and slot 1 of the expansion backplane to bridge the two so I moved 
it there.  The M9302 terminator was in slot 9 of the expansion backplane.

I believe all row D connectors except the empty 10,11,12 memory slots either 
had a card installed or had a stubby little card grant card installed.  I 
didn't pull any of them to see what they were (G727, G7270, G7273?)

...
    BTW - how many slots / backplanes are curently
installed? How many free
slots? How many BUs Grant cards are in open slots? It is also possible
that you will need access to the underside of the machine at some time (to
attach/remove NPR jumpers) so don't mount it where that would be
difficult, until you have the System stable and configured the way you
want it.

I did pull the power cord panel off of the back of the power supply and it 
looks pretty easy to swap the existing power cable with one with a more 
common plug so that's what I'll do after I manage to track down a 
replacement M7095 and get to the point of trying to power up the CPU.

...
    Not too bad - get a 15A plug from any of the Home
DIY places or a big
hardware store. Take off the (should be attached with various screws and
clamps) existing 20A plug and attach the 15A one.  Remember that the the
Black (hot) wire goes to the Brass terminal, the White (neut) wire goes to
the Silver terminal, and the Green (gnd) wire goes to the green (or black)
Ground terminal.

    Your CPU, configured as it is now, will draw maybe 6 or 7 amps from the
wall at 120V, so you're good to go.
