It would have been a good buy. With the right adaptor , it can also do
several types of PALs, GALS, and other devices. Sadly, my S3 is rather
more limited. OTOH, it cost less than ?165.

That will certainly do the job.

The OTP package is identical to the ceramic/quartz package, so no problem
there. The HN462532 is pin-compatible to the TMS2532 as well, so that's no
problem either. Both use a single 50ms programing pulse with Vpp=25V.
