The 2532 _is_ pin-compatible for reading in a PET socket that's
expecting a 2332 masked-programmed ROM. I've had several 2532s in my
PET 2001N-32 (US version of the 3032) since the late 1970s, no
adapter.
These days, it's easier to build an adapter than find real 2532s.

I am collecting bits to build a 6809 machine and I wanted some EPROMS
for the monitor. I found I found 4 x NECD2716Ds which I am sure these
will do fine for that. I and also I think they can be programmed in a
Willem.
So that means the TMS2532JL-45 to quote the full number are available
if any one needs those specifically, for the cost of postage and a small
charge to cover my costs. I bought them in a pile of ICs for around
$7.00 so the costs are small. Note I am in the UK so it might be cheaper
to buy on US Ebay. There seem to be a few available.
