PS. Now only if BOB could make a PDP 11 kit . :(
I think it'd be fun too,
and if somebody else made one I'd buy one, but as
a product -
- there's no legal software you can run on the T11 (and no, RT11 isn't
legal!)
Forth, CP/M68 could be compiled for it. I'm sure TinyBasic can be done
I always fancied writing a PDP-11 Forth ;-)
- there's
no lights and switches front panel option for the T11
It a micro much like 8085 so yes it can be done. But a small SBC with 32kw ram,
2kw rom and some serial IO is a tiny thing.
Hang LEDs off a latch, if you want them...
- there's
no source for T11 chips except to steal them from old hardware
like RQDX3s, etc
That's a bit harder but far from impossible. considering DEC used them in
Falcon boards, and the the qbus slave (kxt21?), Vt240/241 series, and the
storage hub (something mumble50).
Dare I say, clone in an FPGA?
