Err, I think we told you to lock the heads the RL0x's, not RX0x's; the former
use large rigid packs, the latter are 8" floppy drives. AFAIK, there is no
need to lock RX heads when moving them - there is nothing in the manual about
RX drives being shipped from DEC with the heads locks.

Not that I know of, but the DEC manuals (mostly available online) are adequate.

See above.

That's very wise - my last removal, it _really_ helped that I had read the
DEC manuals before-hand, as I wound up performing a removal I hadn't planned
on, and that had a tricky step I probably never would have found on my own,
but which I had luckily read about in the manuals.

Good luck on the move!
