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. Sperry_Printer.jpg (43990 Byte)
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. Sperry_PCB.jpg (69598 Byte)
