I recently acquired a surplus PDP11/44 (my first real PDP11) and it appears
that it is in reasonably good condition, but after opening it up to check
out what modules were installed I realized that it is missing the M7095
control logic module, one of the 5 core modules that make up CPU. Anyone
know where I can find one of these at a reasonable price, or have a good
spare that they care part with?
Also, the keyswitch for the front panel is missing. Anyone know where I can
find one of those, or is there an easy way to bypass the switch?
On the plus side a CMD CDU-720/TM SCSI controller was installed so if I get
the CPU running I hope it won't be too hard to connect it to a SCSI hard
drive and tape drive.

Congratulations! Join the Club.... ;}
A lot of DEC Stuff is listed here ( they also sell on eBay ).
www.jtcomputer.com shows a M7095 - $25.00

Any barrel key will work... one of mine has flutes, but the other ( a
red plastic one marked 'anti static' has no flutes at all.

Depends on the OS you use, and how you generate the new system.
Did you get any other peripherals, especially the disk subsystems that
were once attached? Is the console serial cable present? ( a longish
cable terminating in a DB25). Any other I/O cards? Have you powered the
machine on yet? Be careful of the power supply - they're REALLY deadly
with the covers off. ALso be sure the fan deck is running.
Oh yeah - did you get any Doc with the system... or can you get a copy
of the PDP-11/44 System Technical Manual and the System User's Guide...
these will be most helpful getting the beast to wake up.
Keep us informed of your progress... there are several /44s up and
running among us.
Cheers

ACE XX2247, I've heard you should be able to get these from any locksmith.
I've got one key to go between my PDP-8/e, PDP-8/m, and PDP-11/44.

Sweet! Any OS that supports MSCP disks and TMSCP tapes should work with
this. BTW, for RT-11 you need a minimum of V5.4 for tape support, I'm not
sure what the minimum versions for other OS's are (I think RSTS/E is V9.x).
