Texas Instruments introduced in 1989 with the TI-5322 and its sibbling TI-5332 two heavy-duty desktop printer / display calculators. Main differences between the two calculators is the 12-digit display. While the TI-5322 sports a traditional design, introduced the TI-5332 a novel, tiltable display for a more convenient reading position in POS applications. The design of both calculators matches perfect with the TI-5315 introduced already in 1988.
Dismantling the TI-5322 reveals no big surprises, the printed circuit board (PCB) is centered around a NEC uPD7519G 4-bit single-chip microcomputer. We know this device already from the TI-5310 introduced in 1983. The uPD7519G is a member of the uPD7500 series and matches perfect the requirements of a printing desktop calculator:
|4k Byte program memory|
|256 x 4 bit data memory|
|Integrated drivers for VF-Displays|
|7.63 us instruction cycle time @ 4.19 MHz crystal frequency|
TI-5322 uses a robust EPSON M-260 two-color impact printer mechanism.
