Different pinout, I believe.

I got a few VIC-20 cartridge boards which take two 4K chips. I may be wrong, 
but I have a memory those work equally well with 2532 and 2732 chips. My 
main EPROM programmer only knows 2732 but I borrowed another from a friend, 
and that one does both types of chips.

Anyway, I have far more 2516 and 2716 chips than I have '32s. From what I've 
seen, the 2516 and 2716 are functionally identical, just different 
manufacturers.

Best regards
