I've been searching for introduction dates of early microcomputer

Are you including or excluding systems like the APL-based Intel 8008 MCM/70?

A neat trick since the 6809 wasn't introduced until 1978. I assume
what is really meant is FLEX for the 6800.

I don't think ENIAC used acoustic delay storage? Perhaps what you're thinking

Well, compared to the ENIAC it is! :-)
To be serious, the 29K is fully what we now think of as a 'computer'; that's
