May
we call this huge portable computer a calculator ? No doubt, the TI-95 Procalc
introduced in the year 1986 is a powerful, keystroke programmable calculator.
Some ideas of the early TI-58 calculator and
the never introduced TI-88
influenced the TI-95 PROCALC:
You’ll find an expansion port to install either
RAM or ROM-cartridges and you may connect a printer PC-324
to the calculator.
Already without any expansion the TI-95 features up to 8
kByte of memory, the expansion adds another 8 kByte. The display uses a 5*7 dot matrix instead the
normal 7-segment design to give full alphanumerical capability. A close relative
to the TI-95 PROCALC, the TI-74
BASICALC explains the
typewriter style keyboard.
