I just received email from a friend of mine that might interest some of you
here.
**********************
I've just added a single board computer to my website, which might interest
some of you folks...
It uses a MicroMint 80C52, which has a "built-in" 8K BASIC interpeter. The
SBC has an RS232 port, 8K of RAM and 8K of EPROM. Ity also has an integral
EPROM programmer, which can "save" the BASIC programs in EPROM. Once saved
in EPROM, the computer can "coldboot" directly from the BASIC program, and
run without human intervention.... ideal for situations where a computer
must be quickly / easily programmed for a specific task.
There is also room on the board for an 18 - pin PIC chip, with power,
crystal and reset already wired up... The intention was to use a PIC for the
I/O and the 80C52 for "number crunching"... The PIC can be used separately
or with the 80C52...
The PC board is made using ExpressPCB web service, so all the holes are
plated-through, and the boards are very high quality... total cost to make
one of these SBC's is about $70 - $80. ExpressPCB has a ( free) CAD program
that was used to design the board, and the CAD file for the SBC is available
on my website.
