[Boatanchors] IBM Selectric Terminal

[Carl]

No but I remember the  "memory" mechanical delay line that Sanders Data 
Systems Division of Sanders Associates had in 1968 for their 810 multi user 
word processor.....stolen from Sanders maybe?

IBM tried to steal several patents from Sanders and had to pay some big 
bucks for being naughty.

Sanders is also where Pong was developed. Today it is a thriving part of 
BAE.
