The TI-1200/1250 family has a number of very common 4-function calculators but also a large number of custom made calculators for various customers who may have sold the machines under their own labels.
The TI-1225 is such a machine, made (as the box says) for the True Value Hardware as can be seen here.
The calculator is basically a version of the very common TI-1250 as Datamath Museum tells us. However it is not a common machine and the one I present here is in excellent condition, probably never used

This calculator is based on a TI-1200 and apart from the fact that it is not frequently seen, there is not much that can be said about it.
