Subject: info wanted: Motorola "Educational Computer"
Hi again,
More of yesterdays finds. Picked up a pile of AIM 65 computers with the
keyboards and power supplies all mounted on sheets of plywood. I found one
Motorola "Educational Computer" in the pile. It says "Copywrite 1981 by
Motorola, Inc." on it and has a 68000L8 CPU. Unlike the AIMs, it does not
have a display or keyboard. How did you interface to one of these? Does
anyone have the pinouts and/or the instructions for this?
Motorola used this term for several 68K and 68xx SBC systems.
A good information is at
http://people.delphi.com/paulrsm/68k/mecb/mecb.htm
(BTW:
http://people.delphi.com/paulrsm/68k/68k.htm
is a usefull source for 'old' 68K systems, including
an complete HTML Version of the DTACK GROUNDED newsletter
from 7/81 until 9/83 (excerpt from the first issue:
"...Accordingly, there are a lot of companies who are
planning to drive the PDP 11/70 out of the marketplace
with $10,000 (base price) 68000 systems. It is rumored
that Apple is one of these companies, ..." sometimes
realy nice if you look into past rumors ... - I hope
he will convert the other isues)

and

or

Seems that this system have been quite populat among univs.
There are a lot more sources to find
(and dont't forget Mot itself:
