It sounds like a short narrow single-ended 50-pin SCSI cable, from
that description.

The cables I have match that connection.

No, the same cables work on this device as well.

Yeah, this one was hard to find to begin with :)

It's the Sun "Happy Meal" 10/100 MBit Ethernet SBus card.

This is true--I'm not very familiar with old Sun workstation hardware.

It has the two slanted parallel lines.

Possibly--it looks like it could fit three drives, but there are only
two SCSI ports.

I *think* this is also a "Happy Meal" card...I couldn't get the thing
running long enough to find out :(

The previous owner warned me about that... :)

Really?  That's very interesting...had I known that before putting
them up for sale, I'd have swapped in the SS20's drive into one of the
LCIII's.

Not with the LCIII...it needs to use Mac OS to bootstrap Linux.
