Perhaps they're actually the same box...maybe there's an Einstein-
Rosen Bridge connecting our closets. ;)
Sort of like Terry Pratchett's Library that has all the books in the
universe if you go far enough down the stacks (because all libraries are
actually one library).
All of our junk boxes are actually one - lovely idea. Just have to dig deep
enough to find that old model 73 IBM typewriter I need so badly.

More on the 1967 Electronics Illustrated computer:
Anyone know which issue in 1967 this was in? If I can get that, I can get my local library system
research people working on getting me a photocopy of the article.

When I did a Wikipedia search for "Electronics Illustrated," I found a link to this full set of
page images about another "computer" from that magazine. Not the same as the one sold on eBay,
but still interesting:

I prefer to use marine batteries. They are made in large enough
volume to be inexpensive and the deep cycle ones are more
forgiving of being flattened occasionally.
i'm making a difference.?Make every IM count for the cause of your choice.

Well I'll be dipped. The direct approach paid off! I sent an email to Eaton
via their "Contact Us" form on their website, which I reached by trying to
reach www.bestpower.com, being redirected to
http://www.powerware.com/UPS/BestPower/Products.asp?CC=1 (Service and
support --> Contact Support) and finding the BestService at eaton.com email
address. Or maybe it went to http://www.powerware.com/USA/contact It's hard
Anyhow, someone at BestService at eaton.com sent me a 27-page PDF with most of
the user-side documentation. It includes a pin-out of the DB-25 connector
on the back, and the command guide.

if that is the right article on eBay, then it was in Radio-Electronics magazine if I recollect. I started the same project, but never had enough money to build it. The article was written pre-microcomputer and would have been around 1965-1968. I don't know what book the article could have been in though.
