Editing LINC (section)

== Keyboard ==
The LINC keyboard, manufactured by a company named Soroban Engineering, had a unique locking solenoid. The internal mechanism of each key had a slot that worked with a set of bars to encode the character and another slot that caught a locking bar, which locked all the keys in one mechanical movement of the locking solenoid.

When the user pressed a key, the pressed key was locked in its down position, and all the other keys were locked in the up position. When the running program read the keyboard, the lock was released, and the pressed key would pop back up. This could have the effect of slowing down typing and preventing even [[Rollover (key)|2-key rollover]].

This exotic keyboard was abandoned in favor of Teletype terminals, such as the [[Teletype Model 33]], [[Teletype Model 35]], and [[Teletype Model 37]], in the LINC-8 and PDP-12 follow-on computers.
