Surely you must have a PLCC capable device programmer hidden away somewhere in your not so secret basement lab. And if you don't have one, why haven't you built one up from an HP-85 and some GPIO adapters? I also have a PAC 65. I'll have to open it up and take a look. Wish there weren't so many screws involved. Whatever that 32-pin PLCC part is I should be able to read its contents with my BP Microsystems BP-1610 device programmer. I could program a new one if I had some of the same part on hand. -Glen
