I've seen your posting about the 11/750 and I cannot refute them given
your interests and proclivities, but this happened to be the machine I
first learned VMS on, the first machine I wrote a UNIX driver on, and
one that' I'd upgraded internally many times (it shipped with 512K and
I upgraded it myself to 8MB to give it five more years of use as the
company's main machine for all e-mail, software development and sales
activity).  This machine and I have a history going back some time, so
I couldn't just leave it behind.  The drives weren't stackable (unlike
the RL02s and the RA81s) so they had a large footprint for 28MB each
and I just didn't have a place for them.

I don't know about heads - in a decade of running RK07s daily, we
never had to fiddle with heads - we just kept from crashing our packs.
 Our failures were all electronics and easy to access, diagnose, and

My experience only, of course, YMMV.
