lets leave thermonuclear war to kim jong un and potus.
How about, a nice game of tick tack toe instead?
Probably not Tic Tac Toe first, but I’m going to try for Tetris:

There’s a fellow at vcfed.org that’s also apparently working on a MAME emulator for this system as well. He said it’s booting up into ODT. I can actually write instructions to it in octal, and hand-edit the contents of RAM and system registers. (No wonder the 8 & 9 keys didn’t work. 
) Last night in an emulator, I was able to write a program in the ODT (using PDP-11 machine code) that adds the contents of R0 & R1 together, puts the result in R1, and then left-shifts it twice. I could tweak the program counter R7 to 1000 and “continue” it, or enter “1000G” at the prompt to run it.
Once I get myself a power step-up transformer, I’ll be able to do this on the real hardware rather than the emulator. As for which one will be quieter and more energy-efficient… but that’s beside the point

It works great, but I don’t want to have to lug a 40-lb computer to DMS each time I get an inkling to play with it. Now, mind you, I’m not gonna get one anywhere near as nice… this computer was already expensive enough just from the shipping standpoint 
Perhaps it would be simpler to try to replace the original power supply with a North American PC power supply. If it’s taking 5V@24A, 12V@15A, and -12V@1A, that should be pretty straightforward. You could keep the old supply in a box for completeness, or just disconnect and leave in place, and power from an external supply.

Nah, I picked up a step-up transformer for like $50 on Amazon. I suppose it might be cool someday to put a North American power supply in there and run it off the regular mains, but it seemed like that’d possibly take a lot of extra wire-crimping and soldering… but it would save me from the ~30-year-old capacitors in that PSU now…
