Wang Electronic Calculators - Wang 380 Programmer

Wang 380 Programmer Keyboard/Display Unit, July, 1968.
Sincere thanks to Mr. Takaharu Yoshida for providing the scan of this ad.

The 380 was a specialized keyboard/display unit with internal logic that allowed programs to be executed one step at a time from a built-in magnetic cassette tape unit. Programs were recorded onto the cassette by entering them from the keyboard, and then could be played back as desired from the cassette. This keyboard/display unit could be connected up to any Wang 300-Series electronics package, but was best used on electronics packages that contained additional memory registers to maximize the effectiveness of programs that could be written. The 380 was not a very successful product, as the cassette tape unit was rather slow, which translated to slow program execution performance.
