Umm so why do all your projects end up with PDP 11's or
8's :)
6809 indeed would be my favorite. The 6821 PIA
(parallel I/O) has the RST*
pin, the 6850 ACIA (serial I/O) does not.
As I am currently working a CPLD/2901 homebrew computer design I will
have to say that is my favorite at the moment. A 12 bit op code does
make for a nice 8 bit micro style of computer, and I can manage to
sqeaze in a full 18 bit address space. +-15 bits branches/18 bits calls.
