I know the base instruction set is right but I'm fairly sure the
IO structure is radically different, but --
What peripgherals and OS software is available for, or runs on,
the Intercept? (Not the Jr board, the rack-mount job).
I'm thinking it might make a comfortably modern old machine...
You can run most base PDP-8 software. The small difference is the
console IOTs are differently assigned but easily fixed in the code.
Its the side effect of their IO devices.

Cool! So in what way is it electrically I/O compatible? Did the
Intercept have it's own peripherals (disk, tape, etc)? Or can it
connect to some DEC buss?
All I'm thinking of is a small disk (<= 10 MB), serial stuff (paper
tape, tty) and enough memory to run really old OS stuff.
At this point I'm not very serious, certianly not acquisitive yet.
Just stockpiling ideas.
