Micromint RTC-52/RTCIO real-time microcontroller system:

	3.5" x 4.5" x 1.25" complete
	80c52 processor (floating-point BASIC in ROM)
	11 MHz clock
	64k SRAM installed
	5v-only operation @ 125ma total
	192kbaud RS-232 or RS-485 terminal port
	24-bit TTL parallel I/O port
	8-channel @ 8-bit each A/D
	4-channel @ 8-bit 2us D/A
	battery backed clock/calendar
	screw terminal connections for power/IO
	all manuals

This is a great low-cost, low power microcontroller- I've owned and used 
it for over three years with no problems. The ROM MCS-BASIC is exceptional  
for real-time microcontroller use- with lots of real-time interrupt 
functions, machine-language links, auto-restart from EPROM, reset 
options, memory mapping, user-defineable commands, &c.

It's easy to get started if you have a terminal- I use the serial port 
of my PC with telecomm software, so the RTC looks like a remote 
computer- that way you can communicate/program/store from your PC.
I'll be happy to coach you thru startup.

The original cost to me was over $400 (including SRAM); dunno the 
current price, but you can check with Micromint at 800-635-3355 (FAX 
203-872-2204). They are great folks, and appear to be connected to 
Ciarca's Circuit Cellar magaine, which is a great source for info & 
projects for this and other microcontrollers.

I'm keeping the MCS-BASIC manual (available for $15 from Micromint)- 
this is highly recommended. The hardware manuals will go with the 
computer, and they are well-written with startup and programming examples.
I can supply you with ASCII text of the BASIC programs I use, if 
desired (no EPROM installed, I filled the memory with SRAM)
 
I'd like to get at least $250 for this setup- I'll be taking offers for 
the next three weeks, highest bidder (including COD/insurance) gets it.
