Compared
with the later "Cheapos", this TI-5100 II and its sibling
TI-5200 II feels very strong and
solid. It replaced the earlier TI-5112 and featured
again everything you need for the daily use on your desktop. The TI-5020
looks similar but uses solar cells instead the batteries.
Please note the perfect access to the batteries between the keyboard switches and the display.
Dismantling
the TI-5100 II reveals a surprise: The printed circuit board (PCB) tells the
manufacturer of this desktop calculator: Toshiba, Japan.
Don't miss the US-built TI-5100.
