The
production of the TI-1100 II was shifted about
1987
from Taiwan to Malaysia. Nevertheless was this TI-1100 II manufactured in Taiwan
late in 1989.
Dismantling
this featured TI-1100 II from the 4th design manufactured in October
1989 by Inventec
Corporation in Taiwan reveals a clean design centered around an unknown single-chip calculator soldered on a double-sided printed circuit board
(PCB) and powered by a LR43 battery.
Inspecting
the PCB of this TI-1100 II calculator brought our attention to a small mark reading
IOTI1100IIIA-01A and we started compiling a list of the
PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
In 1991 the design was changed dramatically and we got the TI-1100+.
