I'm wondering how many other
enterprising teachers designed their own small systems for training?
I have a "U of T 6809" board, a teaching aid developed by the University of
Toronto in the early 80s and manufactured for them by a Toronto company. At
one time they were even advertised nationally in one of the Canadian hobby
electronics magazines. It was a single-board system with a monitor/debugger
in eprom, and you'd run it from a terminal. You could develop programs
on-board, or download 6809 code from a host system and run it on the card.
Does anyone else have one of these?

Hi Arlen, nice to see you're still lurking.
The manual I have was a 3rd edition dated 1982, (the 2nd 1981) so he must
have sold quite a few of these. The company was known as CompuKits and
TMK was marketed widely in N. A. His name IIRC Was Jim Reiss. I'll have to see
if he's still at my old alma mater. It's possible the one you're talking about
was a later model if he joined the Uof T faculty.
The built kit looked really neat. Everything was entered from the console by
toggle switches or pushbuttons and it had LED indicators. It had provisions to
expand memory allowing use of Motorola's MIKBUG monitor ROM to interface with a
T-T or RS232 device as well as a provision to add 256 bytes of non-volatile
memory. You could expand memory up to 8k x 8 static ram and suggests you use
the less expensive and smaller chips like the 2102 rather than the 6810s used
in RAM 1 and RAM 2. Would be an interesting project to build one, if I ever get
the time.
