Yikes! If they are true DEC alignment packs, you should consider
finding people who will trade you regular packs for them. Please
do not use them for regular use if they are alignment packs!

As was mentioned in an earlier post, the PDP11 has 16 sectors and
the PDP8 has 12 sectors (did I get that right?). Since they are
hard sectored, they cannot be interchanged.

As I recall, the same pack is used in an RK05F, to get double density.
They achieved this by not letting you remove the pack, so they could
get away with twice the density (5MB), due to the pack not losing
track alignment upon removal/insertion.

There were many makers of RK05 like drives, all of which used the
same packs (as far as I know).
