I guess there is more to an LLF (Low Level Format)
than
I realized. I had thought that a completely blank RK05 media
was able to be FORMATed via an RK05 drive. Your answer
It can
seems to STRONGLY suggest that the media must first
be
SECTORed correctly.
These packs are _hard_ sectored. There's a ring round the hub with
notches in it -- <n> equally spaced ones for the sector pulses, and an
extra one, halfway bettween 2 of the sector notches, for the index pulse.
It's that ring that's different between the 12 sector (PDP11) and 16
sector (PDP8) packs.
