Another thing to be wary of when using Willem programmers is the "twP" setting.

For the most part, you can use the default setting for this, but the older ROM's don't like the defaults...

For 2716, use 50mS for twP
For 2532, use 12mS for twP
For 2732, use 12mS for twP

Using the settings above will give you a much higher success rate when programming the older ROM's.
