What is the difference between an RK06 and 07 ?
Is it capacity?
Yes, in particular number of cylinders. Both have 3 heads and IIRC same number
of sectors.
The RK07 has narrower heads than the RK06. AFAIK the RK07 will not even read
an RK06 pack (I am not sure the servo will manage to

I ask because we have an RK07 at the Update Computer Club.
I didn't know. When did we get one, and from where? We had one many
years ago that I dumped. We might still have the packs
to be sure it gets saved, but I
wouldn't pay the full asking price. Does anyone intend to buy it or make an
offer? If so then I won't.

I have an idea that some of these units used an optical interferometer to
determine the head position
Quite possible. But it also requires the movement control being
different from a standard drive, in order to drive at the precision, as
well as the feedback

For testing there was a cleanroom setup for testing, usually when
working on heads and evaluation of media.

On a special rig, I'm pretty sure. I don't know how the RK06 alignment pack
works, but I am familiar with the RK05 (our machine had them, and we had to
realign one after a head crash), and I assume it's probably similar; it had
