Chip Tester Pro V2 and IC tester demo
Chip Tester Pro V2, Backbit.io
IC tester KT152, Aliexpress, many variants.
A simple TTL/LED IC tester versus the Cip Tester Pro V2.
The KT152 is easy to use and the autodetection works well.
The range of IC's the Chip Tester can test is much larger. Well suited for MOS Technology and many more 'retro' IC's for 5 V IC's from small to large over 40 pin IC's.
Fast support, my request for the 6503 was added in a day to the firmware!
