Yesterday, thanks to Tim Shoppa, I collected some
8" SMD drives: a
couple of Fujitsu M2333 (337MB) and M2382 (1GB each!) drives and an
Emulex SC03 controller. Its my understanding that I might not be able
to use these large drives with an SCO2 or SC03 controller, so, I'm
wondering what I need in order to use them with a PDP-11/73.

From your description of your current SMD drive
controller, it's probably
an Emulex QD32 or QD33, in which case it ought to
handle the newer M2333
and M2382 just fine. I think your first priority should be to figure
out what you've currently got :-).
The SC03 will handle a Fuji Eagle (with a few slight adjustments to take
into account interleaving), but not anything with a faster data rate,
unfortunately.

Alas, it is not one of those. What I have in my 11/73 is an SC02/C for

Ok, since it won't work with my drives, what I really need to do at
this point I suppose is to look for a Fujitsu Eagle. :-) I wonder if
my CDC 9" drive is slow enough for the SC03. Alas, it's not easily
rack-mountable. Anyway, now to figure out a way to get other two
trays of these drives mounted near the top of my 11/73's
rack... hopefully three trays of these drives, and an PDP-8/e on top
of the rack, won't make this too top-heavy. Perhaps I should move the
CPU and expansion chasis, or RX02 drives, to the top position in the
rack, and the six 8" SMD drives to the bottom of the rack, leaving the
TS05 in the middle of the rack. Any thoughts on this?
By the way, does anyone know of any sources for a cheap Q-bus RL02
controller as well as a cheap QD32 or QD33?
