Both answers were right, really. Now that microcontrollers are "popular",
"microcontroller unit" is probably what one is referring to. Originally, "MCU" stood for
"microcomputer unit" which simply meant a microprocessor (MPU) with memory.

I believe those definitions are in a set of Motorola 8 -bit microwhatever data books I
got 15 yrs ago. They're stored away. That year they were brown, my last set of Mot
books were blue. Who cares? Remember the 6809E and friends?

BRs,
