From the Datamath Calculator Museum:

The TI LCD Programmer is a very unusual calculator doing math not only on the base-10 system like our natural life but on base-8 and base-16, too. Long before SW-engineers got nice languages like JAVA or C++ they were used to program the microcontrollers in their native assembler languages. The only operations such a microcontroller is executing, are simple instructions to manipulate data. With the TI Programmer you could simulate these operations, e.g. AND, OR, XOR and SHIFT's in the dataformat of modern microcontrollers (hex or base-16) or oldfashioned minicomputers (octal or base-8). 

From the technical aspects the TI Programmer is at first glance nothing else than a TI-55-II with one removed line of keys to give the layout of the TI Programmer known from the Majestic line. Dismantling the calculator reveals with the CD4569 a single-chip architecture based on the TP0456 calculator circuit family.
