While working on this rather simple project, it kept occurring to me that
the PIC is practicaly begging to be made into a general purpose low chip
count computer. Add some address and data bus latches, static memory, an
EPROM, maybe a peripheral or two. The parallel and serial ports are
practically built in already. Yes, the PIC doesn't have your traditional
data and address bus but with a small 40 pin PIC protoboard like this, it
doesn't seem like it'd be all that hard to interface one to a small SRAM
like a 6264.
PIC interfacing to things like SRAM isn't all that hard, really. I've
been working on a simple little emulated architecture machine using
SRAM and a PIC at its core (I do this because I can, not because it
makes sense. The argument goes both ways in using PICs in projects
like this. ;). There are plenty of resources out there showing you
how it can be done.
