Sounds terribly familiar, Douglas. I went: analog, 6400, 6600, 7600, Cray-1S 
serial 1 (I think), masses of Cybers etc etc, Big Vaxes, PDPs (I handbuilt 
some 
of the early micro-PDPs) and loads and loads of others.

Rei's Hollertith card sounds interesting/amusing ;_) well if you get 
amusement 
out of such things!!!!

Isn't the LUG wonderful
