TMS2532 is NOT compatible with Intel 2732.
*But* it _is_ pin-compatible with the MOS 2332 ROM, so is useful for
I seem to rememebr there are 2 versions of the 2332 -- the 2332A and the
2332B. One is close to the 2732 pinout, the other to the 2532. There are
also 2 versions of the 2364 I think. (I have an old Rockwell databook
which shows these mask ROMs).
I also recall that the active level of the enable (chip select) pins is
mask-programmable on the mask ROMs. On EPROMs it's always active-low. One
to watch for if you're buring your own...
the ROM sockets on dynamic PETs (2001-16N, 2001-32N,
3016, 3032, 4016,
4032, 8032).
When I see TMS2532s float by, I make sure to save them. They are a lot
less common than 2732s.
Of course, you can use a pin-swapper to fit a 2732 into a PET, but if
On the other hand, some programmers can program 2732s but not 2532s. In
that case you might be better off using the former chip and making a
daughterboard to swap the pins round in the machine.
