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:
The
TI-5322 uses a robust EPSON M-260 two-color impact printer mechanism.
