True, but there were ways. ;-)
With an Apple ][ or ][+ with a 16K card, you could lift a pin and keep
the card switched in instead of the ROM during a Reset, so you had full
control.
And even on the later II's, where a non-reboot Reset tromps merrily
through RAM, you can Reset again *quickly* during the boot recalibrate
and get control with most of memory intact.
With a integer card, and the switch in the up position, while a game is
running, you whack re-set, and presto...you are in the
debugger.
Reset into the monitor is certainly a good thing. ;-)
I copied many a game that way.....
Cyber strike comes to mind.
So, those integer cards when placed into a apple II+ are really worth their
weight in gold. While I did have a 16k memory card in to which the integer
basic can be loaded...the integer card is FAR more useful, as it also
doubles a game re-set interrupt system!!!
Ah, but you lift that one pin, and the 16K card works too!

Yes, boot tracing is always my last resort...but it is most helpful
for single-load programs.
