This
TI-2200 II Checkwriter introduced in 1984 is really confusing! The box clearly
states "TI-2200 II", while the calculator itself sports only the
"TI-2200" designation. We knew for years about a TI-2200
II w/o solar cells but it was fellow collector Stefan Klaes who solved the
puzzle in 2008. Thanks!
This
rare TI-2200 II followed the original TI-2200
Checkwriter introduced already in 1982 but is just a design variation.
Dismantling
the TI-2200 II Checkwriter reveals no surprises, even the printed circuit board
(PCB) is more or less identical with the previous design.
The Checkwriter was a very successful product and the line was
continued with the TI-2200 II and the TI-2200+.
A similar product was sold both from Canon with the Checkbook.
