although ENIAC first ran a program it was stored as
acoustic waves
I don't think ENIAC used acoustic delay storage? Perhaps what you're thinking
of is that in the original ENIAC usage, there was no 'program' as we now
think of that term; the machine had to be configured (via connecting up
computing units with cables) for each separate problem, i.e. more
'configurable' than 'programmable' (at least in the Turing machine
sense).
Hence the debate over whether it or the Baby was the first 'computer'.
