Dear All,
I am working to repair a Commodore 8296 and I am in the need of recreating old chips, like PLAs and others.
In some cases I need to write 2532/2532A chips and so the nightmare started.
Looking around I cannot find a modern EPROM programmer that can write 2532A chips (that are the common ones, while "plain" 2532 chips seem rare like a yeti!).
Does somebody know an EPROM programmer that can write 2532A chips?
Thank you

Found a write-up by some one that made an adapter.

A look at my Dataman 48Pro software shows the TMS2532 and TMS2532a (and other manufacturers 2532 chips) are supported in the ZIF socket. PG4UW V3.25.

Most programmers allow you to set the voltage to something different than the default.

Well... I have seen the price of this programmer... I suppose it can even program bananas!!! :)
I knew about the trick to program 2532 usign 2732 layout but I would like to do it... plain!

Uff... this brand too is very expensive. I have found your programmer at a very low price, something around 50$, but it is an old type, an RS232 one!
I have to be true and in my i5 I still have a RS232 port! :D but I am afraid it cannot work on Windows 10, right?

A lot of the old programmers connected to the serial or parallel port and the software was usually ran on DOS or Win 9x, The Needhams EMP-20 list's the 2532, but connects to the parallel port and the software is DOS based. Whatever you end up buying you may need to get hold of an old computer to use it.

In my view, the bottom line is that if you want to program vintage EPROMs, get a vintage EPROM programmer. This may necessitate a vintage PC as well.

When I need it, I run my vintage Xeltek Superpro from the parallel port of a thin client running Win98SE/DOS. Works fine; has networking and VGA as well as USB and real serial/parallel ports.

Oddly enough- I've found things that it should be able to do, but does not. Nothing that writing a custom driver for a JDM programmer could not handle.

Very few EPROM programmers will handle PALs or PLAs. Some will handle GALs with adapters.
Consider this when shopping.

I pretty sure MCUmall's GQ-4x programmer does the TMS2532 , but not the TMS2532A, which it only reads. I have one of these programmers, it works really well. I also found out that it can program the Fram FM16w08 when it is set for a DS1225, which was very helpful in the repair & calibration of my Tek 2465B oscilloscopes. Anyway check their supported device list.

Thank you

Data I/O 201 (which I use most of the times) can program 2532A from firmware rev 4 (I have 5.2)
Digelec 824 can also program them, but I don't like it very much, also there's no documentation about servicing this one.
Finally, my old Promenade C1 clone for the C64 also happily programs the 2532A :)
