The P200 could be easily identified as a close relative of the
TI-2550. Both calculators use the same electronics, the same layout of the keyboard and even an identical
mold for the housing bottom. The different look is achieved through a new mold
for the upper half of the housing and a different style of the memory keys. The
colour of the housing is slightly different,too.
Compare it with its scientific sibbling P300.
Don't miss the rare TXI-8661A based on the Exactra 23 calculator.
