How adaptable is the KIM-1 monitor? IIRC it had both the keypad and
a TTY mode where it would use the UART. I used KIM-1's but never got too
much into poking around everything the monitor could do/did do.
There was also the Apple II monitor with its built-in disassembler
(and miniassembler with the right INTBASIC toolkit ROM, right?) It'll have
a lot of hooks into the Apple II video range but if those are somehow
rip-outable then it might be a start (worse comes to worse, you know that
you can use the PR# and IN# hooks for character in and out). And
also in the toolkit ROM was SWEET-16... Wow, going back a couple
of decades, that was fun back then!
