Oh, we for sure had 8 bit microcontroller chips in 1989. A quick look back through old editions of Radio Electronics looks like you could buy an 8039[0] in 1989 for $1.95 qty 1. PICs were pretty nice back then too.
[0] - An 8039 is a version of the 8048 that was in the original PC keyboard, but rigged up with an external EEPROM for program code instead of the normal mask ROM. They were probably secretly 8048s that were programmed with some other customer's code in the mask ROM, but then fused off for whatever reason.
