Here's a copy of the original Toshiba datasheet for the 8844.
If anyone is interested, I also have 6 NOS RCA 8844 vidicon tubes available. PM for details.
BTW, this datasheet comes from the "TCA Tube Data Cache", published by the Tube Collectors Association. It is a comprehensive collection of registration info and datasheets for almost every tube (over 7000 types) that was registered with the RMA/JEDEC/EIA from 1933 through the 1980s. Includes standard receiving types, CRTs, and all of the 4 digit industrial/transmitting/special purpose stuff, as well as all the registered 1N- and 2N- semiconductor types. An incredible resource for anyone seriously interested in tubes and vintage electronics.
