Sounds good, I have been assuming that if MIT and/or Fred wanted to
get into the business of distributing/maintaining this design they
would have said something by now. I'm on the wrong coast to take the
class :-). 

Other interesting news on the uController board front; in the November
1992 issue of "ComputerCraft" (which used to be Modern Electronics)
there is an article titled "Special Report on Microcontroller Boards"
by Jan Axelson. It contains tables listing 60 boards for 8 bit MCUs
including the 8051 series, Z8 series, and 68HC11 series. It includes
11 systems based on the HC11, but doesn't included the GCB11 from
Coactive so there are at least 12 HC11 systems. I'm going to probably
get the literature on all of them to compare features.

The september issue of this magazine had an article on "Motion-Control
Basics" which had good information on driving stepper motors etc.

These opinions are my own and no one elses, but you knew that didn't you.
