PROMs and EPROMs, specifically 2332/2532/2732

As others have said, normally when putting a smaller chip into a programmer
with a bigger socket you keep the 'bottom row' of pins -- including ground --
in the same position for all chips. A look at the pinouts will show why. But as 
you can read 2716s that's not the problem.

Often 'reverse insertion error' means the chip drew the wrong supply current --
often far too much. Which does suggest your ROMs  are dead :-(
