TI-5230 reveals a typical design of Texas Instruments. The keyboard
to the TI-3500, the printer is borrowed from the PC-100 cradle. But their are many, many integrated circuits...
|Even without the upper
printed circuit board (PCB) the TI-5230 looks
impressive. The layout ot the calculator
assigns one of the 40-pin single-chip calculator chips to the printer and the other to the display.
PCB of the TI-5230 with lots of integrated ciruits (IC's) looking
familiar to us.

makes use of the TMC0501 Arithmetic chip known
from the SR-50 to TI-59 Scientific calculators.
