A cleanup at my workplace has yielded the

dumpster-bound. These will be pickup only in the Houston
area (near Bush Int'l) and may not be available for very long.
Foo! Too far. :-(
- 18 Rk05 diskpacks; NOT the 12-sector type used
on PDP11, these
have 8 slots in the sector ring (PDP8 ?). Don't know what
they came off of.
Real RK05 packs came in two flavors for DEC equipment - 12 sectors
of 16-bit words for PDP-11s and 16-sectors of 12-bit words. Perhaps
you have a pack from some other drive that is mechanically similar,
but not identical. I know Plessey made DEC-compatible machines.
Perhaps the packs are slightly different. The same style of packs
were also used in the IBM 1130, but I have no idea how many sectors
they are. Ditto for RK02/RK04 (low-density version of the
RK03/RK05)packs... not sure how they look.
