Sorry to bother everyone else but I couldn't find a return path to mitccc or
mit-charon.

The question was what is a uCOM-43 and where could a replacement be found.
The uCOM-43 is a single-chip 4-bit PMOS (CMOS version also) processor made
by NEC.  It is a masked program part w/ 2K x 8 internal ROM.  I suspect that
the only place that you will be able to get it from is the stereo manufacturer
(who wasn't being helpful).  I doubt that contacting NEC directly will do
any good, but just in case, here is their address-

		NEC Electronics USA Inc.
		Microcomputer Div.
		1 Natick Executive Park
		Natick, MA 01760
		(617) 655-8833

Good luck.
