TL866II-Plus and 74LS51

I have noticed that a 74LS51 (location C13 on a A2 board) always fails when testing with the TL886II-Plus logic IC test function.

Even if I take one from a working A2 board.

I am using the lastest software version 11.60.

Can anyone here try the same and see what happens?

I found similar

I found similar irregularities with the original TL866.

Ended up getting rid of it.

I've had pretty good results

I've had pretty good results with my original TL866.  However, I don't use the Windows software (don't have Windows), I use an open source one.  Also I've never used the chip testing features, I have only used it to program EPROMs, 2716 to 27512.

The TL866 (and the TL866-II) aren't capable of burning 2716s.  They can't do 25V.

How are you doing it?  Or are you finding 21V 2716s?  They're pretty hard to come by.

I've burned quite a few 2716s

I've burned quite a few 2716s, from a couple of makers, ST mostly though.

 

I run Linux and I use an Open Source programming utility.  I don't know if that makes a difference.

Use 27c16 or 27c32. Both need

Use 27c16 or 27c32. Both need about 12 volts. Problem solved.
