A generic Chinese handheld logic-IC tester sold as the TSH-06F (also "IC Tester", "IC Analyzer", FNIRSI on one AliExpress listing, Fdit / LiebeWH / Walfront / Telituny / Akozon on Amazon): 2 × AA, 16×2 LCD, a 3M Textool 24-pin ZIF, eight keys (O ▲ P Enter / ◀ ▼ ▶). It runs static truth-table tests on 74LS/74HC/CD4000/HEF4000/45-series logic, op-amps, interface chips and optocouplers, identifies transistor types and pinouts, and measures Zener voltages to 5 V. Jeff has owned his "a very long time" and is using it for incoming inspection of the ~130 standard-TTL chips for the KENBAK-1 full-size build (../../IconicMachines/KENBAK-1/).
