Same as the TI-5050 with one memory added. Please notice that the main electronics was simplifies from a 2-chip design based one the TMC1014 and TMS1214 to a single-chip design based on the TMS1115 which doubled RAM- and ROM-size. Read more about the TMS1000 Single-Chip Microcontroller.

Don't miss the twin brother Radio Shack EC-3001 and the similar but different TI-5015.
