Re: I found it! A very sorry looking MK14.
It gets better, or worse, depending on your view !.
I didn't give much attention to the display driving chips, as all segs and digits were active at sometime during testing.
Today I received a TS200 chip tester, and it showed my 7442 is bad. ( It also showed my other 7442's are bad as well. How unlucky is that ?. )
So, without 100% confidence in the display mechanism, I am going to have to get another 7442 or 7445 before anymore testing.
Cheers,
