wonderfully-nostalgic ol' 
 Heathkit analog computer that existed in the '60s?? 
 I could probably answer most questions. I have two EC-1s.

  It was the EC-1 that I was thinking of, and was
hundreds of dollars in the
 '60s as I recall.  Any cover-page art scanned for that to take me back a few
 decades..? 
 I have both manuals for EC-1 on CD. I could send you a scan 
of the cover from both manuals, but there is not a picture of
the computer on the covers. The EC-1 first appeared in the 1960
catalog. Unfortunity, I can seem to find any of Heath catalogs
after 1959.

  The Heath Electronic Analog Computer (ES-400 is the model 
number of just the cabinet kit) was advertised in their catalogs
...
 from 1956 to 1959. I have about half of the kit manuals
for  this computer, and no computer.

  I'll ask, John; what -is- the *exact* Heathkit
part number for the EC-1
 computer assembly and user manuals? 
 When contacting Heath manual replacement service, you just need 
the kit model number.
