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