EAI Pace TR-20 analog computer. As per the labels (see photos) Model 45.0078,
serial number 662. Power cord included. The two latches at the top of the back
cover need a rivet or bolt each, and to be straightened a bit.

In the photos, I have pulled out a module in the lower bank to note that I think
it needs to be one bank higher, based on appearances.

Haven't tried to power it up; not an electronics guy.

Thanks.
