Nothing else than a modified Casio mini-printer.
The Casio mini-printer was borrowed from a good friend and it is wise to keep the fingers away from his calculators. This Sperry Remington is my own, please explore the inside of this unique printing calculator.
|The printing mechanism is different to the Canon Pocketronic. Instead of the Texas Instruments thermo printhead this one is a serial impact printer using normal paper.|
|The calculator electronics is sandwiched below the keyboard. The hardware uses a Hitachi HD3599 calculator chip and a Toshiba driver T1315 for the printing mechanism.|
