In
comparision with all other members of the huge TI-1200 and
TI-1400 line you'll
find here a blue-green fluorescent display. This gives you both a better
readability and a longer lifetime of the 9V battery.
The internal design of the TI-1200 was changed to accommodate
the larger display tube. Instead of the TMS095x and TMS097x calculator circuits,
this one makes use of the TMS1043 single-chip calculator circuit based on the
TMS1000
Microcomputer family.
We know this IC already from the TI-2550
III sporting even [1/x], [x2] and [sqr(x)] keys.
The Dutch department store HEMA sold an identical model as reactor
1265.
