[cctalk] Re: Mechanical Selectric keyboards on video terminals (was Re: Typing class in high school)

There were some video terminals with mechanical Selectric keyboards, one for example being the RCA Spectra 70/752 from the mid/late 60s. For this RCA engineers substantially modified a Selectric 1 keyboard with many new bespoke mechanical parts to output 7-bit ASCII directly. The earlier RCA 6050 video data terminal and models 6051-1, 2, 3 Interrogator used a powered ASR33 keyboard, and the main console of the IBM Office System/6 workstation also used a powered Selectric keyboard. I've been working on a project for the last few years on and off to recreate this terminal's keyboard, starting with fixing a rusty seized Selectric II to operating condition then splitting the keyboard off from the power frame and powering the filter shaft with a motor in lieu of the normal print shaft gear train doing it.
