An HP-25 was a pain to re-program each time it was turned on,
and it only had 49 steps of program memory.

So you left it running on AC all the time?
And next got a 25C?

Ask anyone who lost memory contents of an HP 28C,
much less a 28S, how much work it was to re-enter everything
because it had no I/O (just "Oh!").

Yes, it had "O" (printout!)

Didn't lose memory unless battery door fell off, did it?

To paraphrase the Disney's Seven Dwarves,
"I/O, I/O, it's off to work we go."
