Thanks Bill,
The clone Willem's look cheap enough to buy one to experiment with, even
in the UK. I think I might just order one and give these a whirl.

I have some "TMS2532" chips. Any
suggestions on how to program them (I
have a project in mind that will need these or a similar device)
Data sheet
claims pin compatibility with 2732. I would start there.
My Willem, when powered correctly and strapped for 2732 seems to do
a 21 volt VPP. The TMS2532 data sheet says it wants 25. I don't know
if you can get away with that or not. You may want to spring for some
27c32 chips. They have a 12.5 volt VPP and I've done lots of them on
my Willem.

I'll repeat what Eric Smith wrote, just in case you miss it.
I skimmed the TMS2532 data sheet too quickly and did not give
the pinout a good look. The TMS2532 is NOT pin compatible
with the 2732. The pin changes are minor, and a converter
could easily be made from a couple of 24 pin sockets but
don't try to program it as a 2732 without a converter or a
programmer that explicitly says it will do the 2532.
