Who's got a Heathkit ES-400 or HS-1

John Lawson and I were wondering a short while back, how many Heathkit ES-400 analog computers are known to still exist in the world? It's basically the big fat brother of the EC-1. Here's a picture: http://www.rdrop.com/~jimw/P0758.JPG This one was exhibited by John at VCF 3.0 but is now owned by our good friend Hans and is residing in Munich. There is another in the Computer History Museum's collection. And I have just a front panel to one that I acquired several years back. So how many other people have one of these? And what is the correct model number? I've always known it as the EC-400, but Doug Coward's website says it's correct model is ES-400, but then someone just came to me and said he has a Heathkit catalog listing it as the HS-1. So I'm sure it's either the ES-400 or HS-1, or perhaps both. Anyway, are there any others floating around? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
