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.


It's probably something like a 28F010 / 040 flash chip, or something like that.
Look at which address lines are connected and you can figure out the size of the thing.
Most hobby programmers like Willem etc. will program those, reading shouldn't be a problem at all the foot print of these parts are all the same.
