Out of curiosity, is this purely enthusiast and hobbyist or do people do this for more than recreation?<p>Maybe there's say, large industrial machines (think like an oil refinery), infrastructure level computers (think the elevators of a skyscraper built in the 90s) or say, shipping vessels stuck with these chips and this is actually the cheapest solution, I have no idea.<p>It looks like the end of the line here was the MC88110 in 1992. Don't get me wrong, hobby away, I'm just curious if there's any production reason for this.
