Wow, I wasn't aware that the ODT console needed
memory to run. Checking on
my board, it looks like the 4kw was disabled. I plugged in my 32kw module

was the issue all along.
Oh, of course! You can do very elementary checking of a
switch-and-lights PDP-11 with no memory, but creating any
sort of useful program that will run using only ROM and the
8 registers would be VERY challenging. I suspect you might
be able to get it to print some text on the terminal, but
not a whole lot more. Obviously, no way to call a subroutine
without a stack.
Well, glad you found it!
