Your contribution greatly helps! Thank you! ~ CHAP. -- IBM Computer History: Mainframes: The following was painfully rescued from an ancient VHS tape, and enhanced to increase viewability. It provides a look at IBM promotional computer developments up to about 1970. Many early machines are touched on very briefly, ending with a mention of an IBM customer information and control system used by Houston Lighting & Power Company, as well as other material. Video quality is somewhat poor. Historical value rests mostly with the original audio narrator Norman Rose. Worth sharing for those who love early IBM history. Hope you enjoy.

Contains numerous vintage technical elements such as punch cards, magnetic tape, disk drives,
RAMAC, IBM 1401, DASD, IBM 2260 terminals, System/360, etc.
