Actually there were a couple of Heath [electronic] Analog Computers.
The well known EC-1 and a MUCH larger / somewhat earlier computer [The
Heath ANALOG COMPUTER model ES-400 circa 1957] It sold for $995.00!!!
back then. Sadly, I don't have either system but I do have the manuals
for both of them. I'm in the process of getting them copied [big deal ..
the early one is a 7 volume set] and will probably be selling the
originals on eBay soon. I'll try to get a small portion of the data up
on a website and plan to sell the copied manual sets as well.
A pix of the earlier Heath is up on my site at:
