   The Microchip Technology PIC16C5X series uses Harvard Architecture,
something I wouldn't be quick to call "brain-damaged".  This little
puppy can bang out 5mips or so, so the lack of address space is really
the only problem as far as I see it.
   It has an 8-bit wide register file, too, unlike the General Instrument
part (which I know nothing about save for what is in Eric Smith's
article).
   The combination of low pin count and speed (I think) compensate for the
lack of memory/IO, since for many applications, a 4-bit port and an 8-bit
port are all that is necessary.
   I might also add (in fact, I think I will) that Microchip Tech. also
produces a version PIC16C57xx that has 2Kx12 EPROM and 80 bytes of 8-bit
RAM.  The 2K eprom is broken into 4 511-byte pages.  Maybe if we hooked
an MMU to it?  (It's a joke, son...)

Standard Dis-clamor:

I'm not affiliated with Microchip Technology, I just think it's a funky
little chip that must be good for something.
