Adapter interface for the DEC-T11 CPU and Fluke pod?
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.

Hi Mike, Yes, the 8086 does seem to be the likeliest candidate. I shall let folks know the results. I do have an original Fluke adapter sub-pod somewhere that is designed to go between a pod and another cpu socket, looks like a regular pod but empty and a ribbon cable ending in a 40 pin DIP plug, you just wire it up for the new CPU.

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

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.. ( https://books.google.co.uk/books?id=fBuiNpYlyHcC&lpg=PA61&ots=9xCBtOmX2O&dq=... ) 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.

T11 has 16 Address and 16 Data multiplexed together (AD0, AD1, ...AD15). Hence the 8086. Need a manual... John :-#(# On 04/12/2016 10:09 AM, Mike Coates wrote:
