depends if the T11 is 8 or 16 bit data - I don't know off hand

Is the 8052 a possibility Mike?
Ciarcia's Circuit Cellar, Volume 4 Page 61 mentions he used the 8052
as it
multiplexed the address data buses..

I tried to figure out if the Atari System 2's T-11 could be
exercised with
the Fluke but failed to accomplish anything other than downloading
some
datasheets.

nearest to it is probably the 8086 since that already multiplexes
the
address and data lines (ad0-ad15).

Has anyone here figured out an adapter for one of the Fluke 9010
pods to
be able to emulate the multiplexed address and data lines of the
T11? I
am just starting to look at this as I need to access these lines to
service an old video game board that used the T11 as the main
processor.
Any of you not familiar with the DEC-T11 it is a 40 pin device that
emulates a PDP11 as far as I can understand.
I don't know anything about the PDP11 technically though so am
pretty
much hacking my way through inventing a troubleshooting procedure,
which
the manufacturer of the game - Atari (System 2, Paperboy, AFB, etc,)
-
did not provide.
Just flinging this out in the hopes someone here can help.
Thanks,
John :-#)#
