IC302 is the microprocessor, part numbers are 612-587-0001, or 483520917183. Tritronics lists the part as no longer available, but with a price of $39. This is an older set, but has spent it's life in a summer camp, and has somehow been preserved to look inside and out as though it just came out of the box. If someone has a new/old part or a good pull for a reasonable price, the customer would appreciate it very much.
