Dear Tony Duell
Recently I stumbled across your "The things you find on ebay..."
http://www.classiccmp.org/pipermail/cctech/2013-May/104291.html after I had discovered the
same 'Matchbox' auction you are referring to.
Pretty good guesses you made. The association PDP-8/E and OMNIBUS is correct. But yes
there existed two full-sized buses DEC had rented for the WESCON 1970 show. But yes people
(lets say mostly professionals) back then began to buy computers. But yes the label is
original. And yes it was a promotion by DEC.
Why not try
http://www.ieeeghn.org:80/wiki/index.php/First-Hand:PDP-8/E_OMNIBUS_Ride to
disclose this puzzle. Have fun!
By the way, I very much appreciate your dedication to all this old stuff.
Sincerely,
Remo Vogelsang
