This article is from the Robotics FAQ, by Kevin Dowling nivek@cs.cmu.edu with numerous contributions by others.
A PCB board set designed around the 68HC11f1 microprocessor, which I
have made available as a non-profit enterprise to all you folks on the
net. To help those of you in the US, Daniel Mauch of the Seattle
Robotics Society agreed to act as a distributor.
Well, my first shipment of these PCB's to Daniel lasted about a week,
I didn't realise they were going to be so popular! He has now received
the second shipment from me, so if anyone is interested in these
boards please Email Daniel at dmauch@seanews.akita.com

This board was designed primarily for embedded control and small
robotics applications, and as such it is as versatile as I could get
it. For more details there is complete documentation (in postscript
format) in the file [16]f1v11doc.zip at mit. A number of other F1
related files are available in the same directory.
