Ken S sent me this:
How to read and program a eprom type 2532 with the settings of a 2732.
This is a good trick if your programmer cannot handle those 2532 chips . As they are still used in several pinball machines and as some of my test eproms are 2532 types this can be a handy tool.
We need an adapter socket , only three pins have to be altered.
2732 ................................2532
Pin 18 ............................ pin 20
pin 20 ............................ pin 21
pin 21 ............................ pin 18
Use a Wire wrap socket with long legs.Cut pins 18, 20 and 21.
Solder a rigid piece of wire at these pins.
Bend the wires in a matter that the wire soldered at pin 18 becomes pin 21, the wire soldered at pin 20 becomes pin 18, and the wire soldered at pin 21 becomes pin 20.
As the wires are neatly between the other long pins you can easely insert that in the programmers socket. Use the settings for a NORMAL 2732 an a normal 2532 in the adapted socket to program or nto read. There are some programmers setting for other 2732 types like 2732A or 2732B , these use not 25volts as programming pulse but 21 or 12,5 volts do not use these.
Succes !!
here is the link to the page, it has some other good tips on it as well.
