ZEMCO driving computers

[VintageMusclecar]

Does anyone remember these back from the mid `80's? Below are a couple of pics I dug up on the `net;





These were also sold under MOPAR's old "Direct Connection" deal under p/n P4349443, and under Ford Motorsports also under p/n M-10929-A100. Here's the MOPAR version, haven't found a Ford pic yet.



In regards to function, as evidenced by the pics these computers could be used as a "clandestine" 1/4 mile e.t./mph timer, and also provided 0-30 mph and 0-60 mph figures, and when one wasn't partaking of such activities, it served as a nifty little digital speedometer.

I have an old ZEMCO unit I bought back in the day, but over the years I've lost the setup/instruction sheet. If anyone might happen to have instructions available for one of these, I would really appreciate a copy.
