There are no easy solutions.
If you have a RL02, then you need a 8/a chassis, cables... interface...
...cable ... terminator. Odds are you don't have most of those parts.
With several machines, *I* don't even have all of those parts (never had
any way to link up multiple backplanes)
Well, I bought the cable that interconnects a quad omnibus with a hex
omnibus. So someday when I get an empty 8/A chassis, and that cable
that goes from the RL8A to the first drive, I can get a RL01 running.
If you have an 8/E, I'm afraid an M8433 won't
be any use to you,
because it's an RL8A, which is a hex board, not a quad one. It's
meant for a PDP-8/A.
Uggg... so is there hope of any attainable mass storage for my 8E?
Ideas? If you have a 8/F or 8/M, it is possible to
remove one of the case fans,
and install the hex wide interface into the chassis. Then you just need
the cable for the first drive and the drive terminator.
Interesting suggestion. I don't have either an -8/F or -8/M and would
not have thought of that. Otherwise, You
need a quad wide RK05 interface (definitely available, but
probably expensive),
Probably expensive, but not *commonly* available. the cable (usually not available, but possible to
manufacture),
I'm going to use the one from my RKV11D (since I don't really need
an RK05 on a Qbus PDP-11 full time). It's the same paddle and dual-
40-pin cable set. Plus you need special 16 sector DECpacks to use
with the RK05.
Most rare (unless you find a cache of them). I have many 12-sector
packs, collected over 20 years. I have *two* 16-sector packs (also
collected over 20 years).
