[sebhc] old heathkit computer EC-1 (w/vacuum tubes) on ebay

[William Wilkinson]

Old-computers.com (http://www.old-computers.com/museum/computer.asp?c=787)
says it sold for about $400--which is about $500 less than the number I
remembered.

Looking at the schematic from Vintage Radio
(http://www.vintage-radio.info/heathkit/index.htm), you could probably
build an equivalent from a handful of solid-state op amps and a few
regulators--though I doubt that it would be quite as impressive as the
original.

One thing, though.  You'd still need all that real estate for the knobs,
jacks, and meter.
