Help identifying a PDP-11

Normally the standard under an RK07 is empty, which is what makes them very top-heavy. if you want to remvoe the drvie from the stand, take off the doors and side panels, then there are 4 screws that go up fron underneath through the top fo the stand into the drive. I cna't lift an RK07 drive on my own, it's a stagger-job for 2 people IMHO. If ytou are stuck moving one on your own. it's possible to take it apart into carryable bits without disturbing any alignment, but it's a bit of work. Let me know if you want me to talk you through it. There's an emergency-retract battery (IIRC 8 NiCD cells) which will almost certainly be flat, but more importantly, there's a head lock solenoid which will automatically lock the positioner in the home position when the power is turend off. THere's nothing you have to lock by hand when moving a drive. -tony
