I'm working on a small (VERY small) microcomputer control board to do
things like convert morse code and RTTY to RS-232 serial as well as
FAX to printer codes.  Yes, I do realize that such devices are
commercially available, but it seems more fun this way.  I currently
use a $30 VIC-20 to do these (well, not the fax).  Anyway, it looks
something like:

6502 microprocessor
8 K RAM/ROM (I'll probably use a battery-backed RAM cartridge that
  would be used for both the program and data storage.  It would be
  mapped at both $0000 hex (for page-0 addressing ops and stack use) as
  well as at the top 8K of memory (for reset vectors))
6522 VIA for printer output, demodulator input, timer
one LSTTL IC to decode the memory (probably a quad XOR; it works out
  well for the ghost image of the RAM at the top of memory.)

Anyway, right now I'm looking at using a crystal clock oscillator
instead of a crystal and some gates.  However, I've seen it hinted
that you can hook a crystal directly to the 6502 and get it to
oscillate.  Does anyone have anything on this; I have never seen
anything concrete?
