Terrific Guide Owen.. There's a really great programmer that has been recommended to me that does just about all the chips on older boards, including 2532..

However - it is quite expensive..

I've heard about the Willems and I'll be watching this thread with interest..
 

I haven't seen that programmer before, but it does seem to be able to program all the required ROM's.

For most hobbyists, the cheap Willem is probably the best option if you do not need to program many ROM's. But it does have some issues programming ROM's... It will not always program successfully, even after the power upgrade I described. If you can allow for that, then it is fine for the job.
