Any *short* wide SCSI cables (i.e. 12 inches long)?

50 pin cables/connectors are typically single-ended,
narrow SCSI.

68 pin cables/connectors are typically wide SCSI.

There are lots of variations, however.

E.g., Apple was fond of a DB-25 based SE SCSI port
(along with some wacky pinouts they used on laptops
and docks).

"Old Sun" SCSI connectors were *huge* affairs (can't
recall pincount... probably 50-ish) and definitely
not on any of the kit you mention below.

Internal SCSI connectors tend to be either 50 pin
ribbon cables (recall an IDE drive is 40 pin ribbon),
68 pin "D" connectors (found on drives *with* a
separate power connector) or 80 pin SCA (Single
Connector Attachment -- i.e. SCSI + power rolled
into that ONE connector).

Some cables can be used for differential *or*
single ended applications (i.e. the signal returns
for a SE application become the differential mates
in a differential application).

And, some off-brand cables can be total trash
(they cheat and eliminate some of the returns).

This would be a 411 case.  About 2 inches tall,
beige with "purple" feet, *square* when viewed
from above.  The two 50 pin high density SCSI
connectors are located on the rear, one above the
other.

By contrast, a 611 case is a little narrower,
is most definitely *rectangular*, and has a pair
of 68 pin connectors side-by-side on the rear.

This is probably an 811 case.  Same shape as the
411 (more or less) but twice as tall.

Most *old* Sun workstations have these.  (e.g. 4m
vintage).  Newer machines have 68 pin connectors
(most ultra's, etc.)

If you don't find a buyer, please consider sending it
to one of the SPARC developers on any of the free
eunices.

I can probably find you (or whomever) a faster
processor for this.  Though I may have to refresh
my memory as I suspect the U1 used a different
CPU module than what I am thinking of...

Which card is this?  I may be looking for a 100M card
if I resurrect my LX...

I suspect that should be:
2  25 pin SERIAL ports
1  25 pin PARALLEL port

<grin>  The icons adjacent to each port take some
getting used to before you can sort out what the hell
they are trying to depict!

> 1 SCSI port (I don't know the type)

I think the U1 still was 50 pin *narrow*.

> Integrated audio

Hmmm... that doesn't sound right.  Perhaps you are
refering to an MII or parallel port?  (does the icon
look like two PARALLEL -- though slanted -- lines?)
Sun has all sorts of oddball adapter cables to get
from the back of "whatever" machine to "something
more traditional"...

I think the U1 can accept one 1/3 height and one 1/2
height?

As above, I would be interested in this if I resurrect
my LX...

I ran NetBSD 2.0.2 for some time on a quad 70MHz(?)
SS20 and was quite happy (though the case gets hot
enough to toast bread!)

They'll take SE SCSI narrow drives -- like the SS20.

I may have some assorted cards for old Macs for anyone
going this route...

(I never liked running anything other than MacOS
on Macs because of the problems booting headless.
Perhaps this is different on Linux?)
