Subject: A classic present - the "Instructo Paper Computer"
One of my co-workers just dropped off a fun little thing at my desk - a
McGraw-Hill publication from 1979, the "Instructo Paper Computer"...
it's like the Bell Labs Cardiac. I'd never heard of the Instructo before.
Digging around on the 'net only found this...
http://www.computermuseumgroningen.nl/mcgrawhill/ipc.html (is Allard Shaap
here on the list?)
In case this spawns a CARDIAC thread... start here ->

Fiber-based computing... big fun!
