I'm confused - or is the above post just a joke ?
Since I couldn't get DOSEMU to drive the par-port programmer and
the edit-program-test cycles became tedious I've suspended my
PIC project. And I know that PIC have extended the range.
[ Did anybody test the dspPIC ? ]
But how can a PIC be an overkill and more expensive than a proper
microProcessor like 68HC11, 8051 ... ?
