So, long story short, all you need is a list of all the machines that say they are 'processor'? It was a short-lived hack, and none of those are made anymore, AFAIK, so your list will be finite and short.
IIRC- every machine supported by the hp backend calls itself a processor, and some (all?) of the machines supported by epson/epson2, but I've never heard of any other machines that did it. allan -- "The truth is an offense, but not a sin"
