Looks like you either have mass storage you don't
know about, or you
have an "entire" OS in ROM.
Though, as a question, do you have semi-conductor RAM or core RAM?
Becuase, if it's core quite amazingly you might have the last program
that ran on the 8/a still in memory (though, that's incredibly
doubtful). If you have semi-conductor RAM, you might seriously want to
consider trading your bootstrap/powerfail card for something
different, mostly because it would be somewhat annoying always booting
into the previous device's OS.
As an idea, have you tried running the system WITHOUT the
bootstrap/powerfail board? You can quite possibly alleviate this
problem by just not having a ROM board present. (Though, as an idea,
you might wish to get the ROM chips dumped and the images put up on
the internet, as some might find the in built software interesting;
also, while it's out you might be able to load ROMs of programs that
will be useful to you (such as, for example FOCAL or BASIC (or both!)
in ROM, giving you a useful system).)
Cheers to you.
