I have (order year ago) TTL chip tester TES200. Not well from my point of view because support limited sets of chips. I think about new one, found several variants.

  1. TES200 (I have)

  2. TrolSoft - very good variant but too expensive from my point of view (aprox. 100 usd)

  3. Mega-IC-Tester - Opensource tester, based on arduino 2560. Cheap and usefull.

Will try to build Mega-IC-tester. In case of unsuccessfull probably order one from TolSoft.
