The first time I saw a 4114 (it was in the engineering part of building 63), it was running Asteroids.
I was responsible for 4107 Option CX, a field-installable board that enabled IBM 3270 emulation. I did the hardware and board firmware, Steve Houchin did the terminal firmware. The 4107 CX board design was licensed from Digital Communication Associates and was basically a Tek layout of their IRMA card. The 4207 board used a faster processor (Fairchild 8X305) and had dual-port ram. I worked all night debugging that board to demo it for Dave Brown, and slept under my desk. Later I did the terminal firmware enhancement to allow connection to hosts running SNA, Systems Network Architecture.
