You can get proms burned here:

Does the output have to Open Collector?
I was thing of substituting a 32x8 tristate prom.
Also while all the derives you've mentioned are I

being read (that is, as they are normally used in the circuit), the
programming algorithms are different for differnet manufacturers. You need
to get one that your programmer can handle
