Purchased at an estate sale on October 23, 2022 (alongside Radio Shack TRS-80 PC-4, Radio Shack TRS-80 PC-1 Cassette interface, Radio Shack TRS-80 Aviation, Sun Hemmi 341 3215, TI 6200, Commodore SR4912, Texas Instruments TI-1025, Texas Instruments TI-32 ). The unit is tested and functional, however the battery pack has exploded as is common with these models. The internals are uneffected by the battery corrosion save for one of the battery conacts which has snapped. Externally this unit is in great condition, a new battery pack will be a project for the future.
