I've just been emptying and old piece of computer kit for salvage (mainly for the box) and there are a load of these chips in there. I know they are a "not available to the public" version of a PIC chip but I wasn't able to discern which type they are and whether they are worth salvaging (read: reprogrammable).  I imagine not but, before i throw them away, i thought i'd ask if anyone knew.

Thanks
