I was gutting some stuff that I am going to toss, and one of those things was the aforementioned apple keyboard. Inside I found a chip labeled as followed:
NEC Japan 8801H7 (Manufacturer and date code?)
8048HC610 341-0124-A (NEC's part number followed by Apple's part number?)

Question, does anyone think that this is an Intel 8048 compatible microcontroller. After all, it does look like NEC made such things:

The 8048H bit seems like a bit of a match.
The reason why I'm curious: it would be fun to adapt keyboards using something like an AVR or PIC. But it would be even cooler to examine the ROM of this chip (if possible) given that the keyboard is designed with what amounts to the PIC of the late 1980s.
