Heh... I have one of those too, but it's an RK05F-16. After years of
looking, I recently aquired an RK8E interface, but I have no RK05F
drives, just several RK05Js in various states of foam decomposition
(one was used recently by me and by Jerome Fine, but most of the others
haven't been spun up in a number of years).

I have done RK05 alignment with ordinary data packs, but I wouldn't
guarantee that the drive would then pass the "pack interchange diagnostic"
where you take two (or more) drives, write on one, then move the pack to
the other to read. The drives I aligned (for my employer, not my own),
worked fine with everything we had in the shop, but I was never confident
that they were aligned as well as they would have been if I'd had an
alignment pack.

If you ever come up with a solution, I'd love to hear about it.

Fortunately, I still have a few new-in-bag absolute filters (for both RK05
and RL01/RL02), but those are a scarce resource as well.
