TI-2200-II_84_P1.jpg (186127 Byte)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!

TI-2200-II_84_Back.jpg (199349 Byte)This rare TI-2200 II followed the original TI-2200 Checkwriter introduced already in 1982 but is just a design variation.

TI-2200-II_84_PCB.jpg (257452 Byte)Dismantling the TI-2200 II Checkwriter reveals no surprises, even the printed circuit board (PCB) is more or less identical with the previous design. 

TI-2200-II_84_M1.jpg (212535 Byte)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.

 



The TI Checkwriter is featured in the Texas Instruments Incorporated bulletin CL-855A dated 1985.
