The RIM loader is a very short sequence that is typically toggled in
from the console; it's job
is to load RIM
(read-in-mode) format paper tapes. It can handle loading
only into one field
and it does no checksumming of the loaded tape to validate it was read
correctly.
The BIN loader is a longer set of code that is typically loaded in from
a tape in RIM format.
Most of the system software, diagnostics, etc are all BIN format paper
tapes. BIN loader
can handle multiple fields and does checksumming of loaded blocks for
validation.
The DEC small computer handbook for the PDP-8 series:
http://computer-refuge.org/bitsavers/pdf/dec/pdp8/handbooks/Small_Computer_…
has listings of both of these loaders on pp. A-31 thru A-34.

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.

as discussed in the irc its core ram yes and i have the os on paper tape if
anyone knows how i can hook up my h10 to my laptop to copy the tapes / take
the bin's of bit savers to make tapes from??

the cards i got
M8315 ? KK8A PDP-8/A CPU board (hex wide)
M8317 ? KM8AA PDP-8/A bootstrap, powerfail (hex wide)
M8316 ? DKC8AA PDP-8/A I/O serial/parallel/clock (hex wide)
G649 ? MM8AA 8K Core stack.
H219A ? MM8AA 8K Core memory control.
