CP/M TCP/IP (was Re: CP/M coding question)

        Take a look at the Zilog EZ-80 or Z84C15. The Z84C15 has everything you
should need as far as peripherials. Just add FLASH and SRAM.

        Some of the high end PICs might be applicable, but personally, I can't
stand the little buggers. Other choices might be the Atmel Mega128, or one
of the TI MSP430s with dual UARTS. The difference is that while the Z84C15
has real UARTS with real handshaking lines (the venerable SIO core), all
these other UARTS are basically 2 wires. You want handshaking, you'll have
to manage all that yourself. Not rocket science, but it is extra code and
hardware.

        The real problem is there are *way* too many choices in micros that will
fit the bill for what you want to do. Start going less mainstream, you've
got the ARM cores, SH/x series from Hitachi (verra nice parts), custom x86
cores, PowerPC, ST9 or ST10, yada yada yada. For projects with sensitive
production costs, you can really get down there, but at the cost of going
with questionable tools and suppliers.

Right now I'm looking at either a Z80 with 32k of ram, 16k of flash, a CTC
and one or two DUARTS, or a uC that'll provide as much of that in hardware
as possible. PICs are nice, but generally seem to have too little memory
for TX/RX buffers, and Basic stamps are too slow. (and who wants to
program in BASIC anyways?)

Any suggestions on a good uC to use?
