I have a Heathkit EC-1 analog computer in operational

the patch cables, assortment of caps and resistors plus the operating

help fund a 1939 pre-war television acquisition. A dilemma. Should I
part with the EC-1 I doubt I will ever find another. As toward the
value of the EC-1 I don't have a clue but would like to know what
anyone else thinks a fair price would be.
FWIW, I was just in the middle of purchasing one. Right *after* the
paperwork and logistics for the deal was complete, the seller accepted
another offer of $1700 for *my* EC-1.
So, that appears to be the going rate for a pretty-good condition EC-1.
In the process, I did manage to get the assembly manual for an EC-1, so
now that I know how expensive they are, maybe I'll just build my own. If
I get the time, I'll try to scan and web-ize the assembly manual. I don't
recall seeing any hard-to-get parts in the parts list.
I don't have the operations manual, but the assembly manual did include
the patch-configuration for a bouncing ball simulation and one or two
others.
I'd say the EC-1 is a pretty good candidate for the first personal
computer. It was intro'd in 1960 for around $300.
