Connecticut Technical Corp
Little is known of Connecticut Technical Corporation. The Connecticut Secretary of State website lists a company by this name, but one that was founded many years later. There seems to be no record of the company in question.
Their keyboards were described briefly in Computer Design magazine in December 1965 in the article Manual Input Devices [CD1965-MID]. Their implementation was described as a “motor-driven mechanical device with switch closure output”. 8-bit output code generation was provided. The encoding switches were rated for 48 volts at 1 amp, which is significantly higher than the rating of later mechanical switches that were expected to handle only a few milliamps of current. The in-built mechanical interlock could be remotely engaged, preventing keys from being struck.
A single photo of a Model KB-100 alphanumeric keyboard is included in the article; this is a 65-key keyboard.
Connecticut Technical later placed an advertisement in Modern Data magazine. No details on the keyboards were provided besides the claim that these keyboards were “tested to 100,000,000 operations per key with zero mechanical or electrical failures.”
Patents were issued to Connecticut Technical Corporation for a “Bowling ball cleaner” (1963), an “Automatic cycling system for pin setting machines” (1965) and an “Electronic beat producing device” (1966), but not for any kind of input device.
