I would label this a finite state machine more than a computer. Still, if it got the job done, great. It doesn't say when he created it, but if it was any time in the past 15 years, a microcontroller would have been smaller, cheaper, and easier.

Judging from the 74C logic and 2716 this was designed more than 20 years ago. In today's situation only expensive component in this thing is the 2716 (or just about any (E)PROM) and I believe that even few years ago this thing would be in single quantities cheaper than using microcontroller (although not significantly).
