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.
