Purchased at an estate sale on October 23, 2022 (alongside PS-6200, Radio Shack TRS-80 PC-4, Radio Shack TRS-80 PC-1 cassette interface, Sun Hemmi 341 3215, Texas Instruments SR-50A, Commodore SR4912, Texas Instruments TI-1025, Texas Instruments TI-32 ). This is an aviaion program for radio shack pocket computers. Not too sure if it works as I don't have a proper cassette interface for mine.
