The dismantled
TI-5230 reveals a typical design of Texas Instruments. The keyboard
construction is
similar 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 of the calculator assigns one of the 40-pin single-chip calculator chips to the printer and the other to the display. |
The upper PCB of the TI-5230 with lots of integrated circuits (ICs) looking familiar to us. |
Surprise - the TI-5230 makes use of the TMC0501E Arithmetic Chip known from the SR-50 to TI-59 Scientific calculators. |
