The answer is to construct an adapter.

I've used one for years on a vintage programmer, that was recently replaced.

To make an adapter you need two 24 pin IC sockets. One with solid pins and one normal one.

Plug the regular socket in the one with the solid pins. But Bend out 3 pins,
18,20, and 21

I'll call the top socket pins T and the bottom pins B

Connect as follows:
18B ----> 20T
20B ----> 21T
21B ----> 18T

That's it. The only other concern is the programming voltage.
A 2532a is 21V and a 2532 is 25v

Your programmer must be able to have a setting for 2732 that will supply the correct programming voltage.

One final thing, you must attach the top socket to the bottom socket.
Not shown in the photo is wire wrap wire used to physically attach the end cross bars on the top socket through the base holes on the bottom socket. This step is needed because once the programming is complete and you attempt to remove the IC from the top socket without this step you could easily pull the adapter apart.
