Correction, directly from the manual. RL01 or RL02 emulation ;-))
But serious, there are two version of the SC02 board. The SC02/L emulates
the Rl01/Rl02 disks, and the SC02/C emulates the RK06/RK07 disks.
Looks to me, that the big difference is in software, because both of these
boards look very similar.

Well, technically the Eagle is a 10.5" disk. Other Fujitsus, like
the 2284, are really 14" (and they have a nice transparent cover
over the HDA so you can see the disks spin and the heads seek...)

Most 5.25" SMD drives are rather modern and have data rates too high for
the older Emulex (and other brand) SMD controllers. Newer Emulex
SMD controllers, like the QD33 and QD34, don't have a problem with
the high-data-rate SMD drives.

The disks you are looking for are SMD disks - 60 pin digital cable for all
drives, 26-pin data cable for each drive. Yours must support two physical
units.
I have used 14" (RA-81-sized) disks like the Fujitsu Eagle and have seen 5.25"
disks, but never used them. I know that SMD disks are available in the 600Mb
range. I don't know how small they get. I can't imagine how you'd map
hundreds of megabytes into several dozen RL02 images, but in the interest of
compatibility, I guess they'd have to do it.
On VAXen and PDP-11's, I've always used a Systems Industries 9900 controller
to attach Fuji Eagles (and some other sizes) to the Massbus. I have an SI
Q-bus controller that appears to talk to the 9900 (dual 40-pin connectors),
but I've never used it. I have KDA-50's now (and wish I had docs for the
CS-21 SCSI card).
Bottom line - SMD disks are hard to find, but they are out there.

Depending on the drive and configuration used determines if it will emulate
an RK06 or an RK07.

Nope, it is a Q-Bus ...

Emulates RL01 & RL02, or better said the RLV11/RLV12 controller. On bigger
disks, the controller maps up to four logcal units per disk

The SC02 is a Qbus SMD controller. The SC12 is the Unibus version. I
glancing around I have a bunch of copies of the SC12 but only 1 on the SC02.
Contact me off list and we can work something out for getting you a copy.

This is an SMD drive controller. Is it a hex-height card or a quad? All
my SC02s are quad-height Q-Bus controllers.
An SC02 can handle two physical SMD drives. BTW, I think you mean one
60-pin and two 26-pin (not 36) connectors. There are several versions of
the firmware for SC02s, emulating different DEC drives. I don't have my
manuals to hand, but IIRC the -C version emulates RK06/7. Depending on the
size of the attached physical drive(s), it will emulate several logical
drives. You might find a manual at
http:://rsxbbs.delconet.com/docs/emulex/
but the site doesn't seem to be up at the moment so I can't check :-(

If this is the one I'm thinking you have, it is more like an RL02,
RK05s are front-loading. This is the "take the bottom off the
pack, put it on the spindle, and put the bottom over the top of the
pack" type... no?
No, it is not, this _IS_ the front loading type. But I would believe
tat if Plessey
made several versions, they all might be rather similar as far as the
interface
is concerned.
If so, I belive I have the service docs on it... must wait to get
home tonite to see for sure. I gave a PDP 11/04 system to a
Listmember which had a pair of these attached. I have written him
offering copies of these dosc but so far only silence has returned to
me.....
HINT HINT you know who you are.
Anyway..

I can copy this as well for any others with the drive in
question... let me know. I will post the exact model the docs are
for this evening.
