OT: Who made this Vacuum Tube Flip Flop Monostable Multivibrator (1955) & ...
Apologies:
OT: Other. What Company made this Vacuum Tube Flip Flop Monostable Multivibrator (ca. 1955 ?) & what machine was it used in ? FF-2 DRA34376 09975 7-5-55 It looks too new to be Whirlwind, ( definitely newer than Colossus, Bombe, Einiac ). And also a bit newer than Univac 1103 and the IBM 703 (?). A prototype ? Could "DRA" = Draper Labs ( or some MIT collaboration ? ) There are several versions: FF-1, FF-2, FF-4, so different vacuum tube monostable multivibrator Flip Flops, having different logic functions. Anyone know, or know someone who might know ? thank you, |

I have seen something similar in Marconi Radar stations from the 1950~1960.
Please VOA, please BBC, please Deutche Welle.... Don't surrender the shortwave bands to China Radio International. |
