i wonder what the story was behind the 68000. did they design a cpu core for the future and then wrap it with a compatibility layer to meet the market or was it simply all they had to ship given time and/or engineering constraints.
- bryanlarsen 2y agoPackaging would have been one constraint, among others. It came in a 64-pin DIP, the largest available and broadly supported at a time. No room for 32 data and 32 address pins + everything else they needed, without muxing which would have eliminated some of the benefits of the wider bus.
