This might be of interest to somebody here (hopefully)...
Surplus Traders (
www.73.com) currently has 35 Nabu computers for $29.00
a pop, plus shipping. Normally they do bulk sales, but they will sell
the Nabu individually. (Search for item CR356.)
I picked one up a while ago, and mine was still 'new', in the box, with
a factory seal. Then again, since this surplus, it might be best to
verify that the units are 'new' if that's important to you.
Unfortunately, I haven't really toyed with the Nabu hardware too much
(yet), and if anyone else has, I'd love to hear about it. Either way,
these machines are certainly an interesting part of computing history.
Here's a small blurb about the Nabu:
