Congratulations Dave.
I have only seen one up close - one time.
About 15 years ago I did get ahold of most ot the manuals from the heathkit
manual replacement service, all except the es-600 function generator manual.
I still have not found a reason it is called the HC-1. I just call it the
Heath Electronic Analog Computer Model ES-400, because es-400 is the model for
the cabinet kit.
I have a magazine cover about the Heath Analog Computer at
http://www.cowardstereoview.com/analog/readlist.htm
I've envious, Good Luck with it.

Yes, I'm confused about that too. Here's what I just said to another
listmember about that privately:
You know, I've been wondering about that. Nowhere have I seen any
reference to the "H-1" model name. Not on the machine, not in the docs,
nowhere. The former owner referred to it as such, and some googling
turns up a few pages describing this machine and calling it by that name.

Thanks!

When you learn more, please consider doing a writeup for
old-computers.com. I'm sure they'd love to have a page for your new find.
They do have a writeup for a similar, but smaller computer: the EC-1.

I hit ^X too soon. A bit of crosschecking tells me that your machine is a
Heathkit ES-400 and was released in 1956. One seems to have appeared on
Ebay in the past few months.
Here's the manual:

Thanks for the heads-up Will; I have a copy of this already. One
came along with the H-1's docs.

Ah ha, I was wondering where your site went. It was helpful when I was
first working on the Tyrotek analog computer I have.
I was recently contacted by the family of the founder of Tyrotek, who
gave me some of the history of the company.
