Does this
KMC 2000 calculator sold in 1984 by
Kmart Corporation look familiar to you? Please
compare it with the TI-1788 or Privileg LC 6000,
Radio Shack EC-303, Systema LC1400 and probably many more
offspring.
The
KMC 2000 calculator introduced in 1981 combines in a
very compact package both a calculator with 3-Key Memory and a clock with alarm-time. We know similar, but
larger products including a stopwatch since 1978 with the Canon
LC Quartz, Toshiba
LC-833WA, and Texas Instruments
TI-1790.
Dismantling
this KMC 2000 calculator manufactured in May 1982 by a
non-disclosed Original Equipment
Manufacturer (OEM) reveals a very clean design centered around a NEC
uPD1032G single-chip calculator circuit soldered on a double-sided printed
circuit board (PCB) and powered by two small LR43 batteries.
Inspecting
the PCB of this KMC 2000 calculator brought our attention to a small mark reading
CC-31 A1, we noticed similar marks already with the TI-1788,
TI-1788 II and
TI-1788 III, the latter manufactured by
Cal-Comp
Electronics and started compiling a list of the
PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
