[sdiy] Ebay keybaord and analog computer

[Tim Parkhurst]

Hi All,

A couple of interesting goodies found on Ebay; 

What looks to be a fairly nice keyboard (just what exactly is a "waterfall"
keyboard?)

And a VERY interesting Analog Computer! Apparently some sort of Navy
training device, this could be a blast to tinker with. It includes an 8-bit
d/a, an 8-bit a/d, 2 summer-integrators, 2 summers, 1 diff amp, 1
comparator, 1 multiplier and a function generator. A little bit of patching
(it uses banana plugs), and you've got a synth voice!

Watch for the line wrap on the URLs boys and girls.

Okay, now get back to work!

BTW - There actually ARE idiots bidding on "Google Glug" caps on Ebay. One
is up to $15k!
