Unless I've missed something, that's two connectors. The lower one
is a 2x3-pin connector; it carries DC for the drive electronics. The
upper 3-pin connector is AC for the spindle motor.
This looks like a model 801 or similar. I think the docs might be on
Bitsavers. What model is it, for sure?

Well, the label on the photo says "Shugart 801".

Oh, and about a card for your '11...Is this your Heath H-11? A
standard RX01 or RX02 controller won't talk to this drive, but there are
a great many third-party controllers that should, and will emulate an
RX01 or RX02. But let's concentrate on getting it powered up first.

Have a look at page 22 of this manual for the drive on bitsavers. Pages 18 and
19 describe the pinout.
http://bitsavers.org/pdf/shugart/SA8xx/50574-4_SA800_OEM_May80.pdf
Another thing to worry about is whether the drive motor matches the mains in
your area. There should be a metal label under the drive at the front which
says what model it is and what voltage/frequency it expects. The motor should
say the same. It's probably okay but it doesn't hurt to check.

If memory serves, the OEM manual for the 801 on bitsavers does have
the connector type numbers--and they're still made.

Worst case, you could probably also order them from Digi-Key or Mouser. Not sure what
their Canadian shipping prices are like.

There were power "bricks" with all of the DC voltages made at one time.
+ and -- 5 and 24v was a popular item at the swap meets.
It does have an ac motor, and there were at one time parts to change to
50 hz. I don't recall if the voltage problem is strappable, or has to
be handled externally with a stepdown. Never worked with the floppies,
only with SMD drives at 50hz for export.

ebay auction for open frame supply for 2/3 of the voltages:
140670971601 +5 at 5a +24 at 4a.
Getting the -5 is only necessary on an 800L I noticed in the manual, do
you have an 800L?
I recall that not all 5v supplies at the time were happy in a system
supplying as -5, but I don't recall how to tell which you needed. I
think that would take some research to figure out from the type of power
supply. Also there are implications with the AC in and grounding which
come into play. It was always nice to find the triple output supplies
and not have to deal with a separate -5 supply.

If you wanted a new supply that's not likely to fail any time soon, you can get lots
of 5v/24v/-12v or 5v/24v/-15v supplies from Jameco for around $50. If the manual is
correct (page 19), you can use the -12v/-15v with some jumpering. If you wanted to play
it safe and not jumper it, you could always drop (raise?) the -12v/-15v to -5v with a
7905; it uses 0.1A max, so you'd probably at least want a small heatsink (you'll
be burning 0.7W/1W), but nothing too huge.
Power supplies (all can handle the spec'ed 1.7A on +24v):

I've seen bricks for modems with +5 and +/-12 and still have a pile.
I can't recall seeing a brick with -5 and +24, however. What would
they have been for? And would they be able to supply the necessary
current (in particular for the +24)?
Open frame linears and switchers with all of the voltages were quite
common, however.

I seem to rememebr that some 8" drives needed a -ve DC supply rail too.
The electronics needed -5V, but there was a 3-terminal regulator on the
PCB that could be connected or not by jumper options. SO the drive migth
want -5V, it might want a bit more (often specified as -12V). Worth
checking the links _bfore_ powering it up.

I thinmk there wwee 230BV motors made. Iv'e enver seen oen thart could
bn strapped for differnet voltages (well, OK, I've seen motors that could
be strapped for different voltages, but not in 8" floppy drives).
A lot of 8" drives over here (UK, which is 230V 50Hz mains) were 115V
ones, run of an autotransformer. Obviously they were 50Hz motors/pulley
sets.

Not sure what their Canadian shipping prices are like.
Worst case, you can use individual pins (IIRC, sames as 5.25" connector)
and mold your own insulation around them. On my first one, I just wrapped
each pin with electrical tape (which is a risky way to do it)
BTW, 8" drive power requirements are not completely standardized. I
needed different connector? and one different voltage to use a Tandon 848.
I had access to LOTS of 5.25" bare pins and used connectors, due to my
previous partnership in Elcompco, making and peddling 5.25" 2 drive units
with smoked plex covers.

Hot melt glue is perfect for this, as it's a wax more than a plastic,
and fairly easy to remove, and is inexpensive - both the gun and the
glue sticks.

I';ve seen at least one 8" drive where the DC power input was a
single-row hreader plug at 0.156" spacing.

AFAIK 5.25"-type power conenctors are still easy to get new. So are
similar size pin and socket contacts.

Let's not forget the dreaded Calcomp (103?) drives that used a 40-pin
header to handle both DC power and signals. Woe unto you if you
plugged the connector in upside-down...
Were there any drives that used an edge connector or header to also
supply AC for the motor?

I would hope not. Fortunately every 8" drive I've worekd on has used a
sparate connectore for the motor power, not mounted on any PCB, but I
ahve seen sevearla different types of connector used.
I have worked o na little HP strip printer (I think an HP5055) which
feeds AC to the motor over the same card edges and edge connectors ans
other (isolated-from the mains) signals. but thsese conenctors are hidden
inside the unit, the user is not expected to make connections to them.
