This is not what I thought was going to be the next post... but here it is anyway...


Many of the cheaper EPROM Programmers do not program 2532's as default. This is frustrating, as there are a lot of pinball and arcade machines that use these ROM's.

But, there is a trick...

2532's and 2732's are basically identical... except for the fact that some of the pin's are in different places! 


There are only 3 pins that need to be changed...

2532 pin 18 -> 2732 pin 21
2532 pin 20 -> 2732 pin 18
2532 pin 21 -> 2732 pin 20

If you make this into an adapter board, you can program as many 2532's as you like using the 2732 setting.

This works well on the Willem programmers, which do not have a 2532 setting at all.
