This calculator was introduced one year after the TI-5100 and features 12 digits of display size instead of 10 digits.

TI-5200_USA_PCB.jpg (131235 Byte)Dismantling the TI-5200 reveals a similar printed circuit board (PCB) like the TI-5100. Main difference is the 40-pin TMC1278 instead the 28-pin TMC1073 of the famous TMS1000 Microcomputer family. The reason is found in the necessary lines to drive the 12-digit Fluorescent display.

The differences in the weight result from an "optional" metal plate inside the calculators to give a more stable feedback of the keyboard entries.

About 6 years after the introduction of this TI-5200 its successor TI-5200 II hit the market.
