So yesterday I went and picked up a couple of computer systems,  and a
couple of boxes of "cables and other stuff",  which turned out to
contain some rather interesting stuff...

The computers are an H-P and a Compaq,  and I haven't opened them up yet or
fired them up to see what's in them,  no idea yet.  I have a Dell box
sitting here too that I need to figure out,  and that's not gonna happen
till after I get this "test fixture" out of the way,  where I'm
testing some SCSI drives...

Anyhow,  I also got another flatbed scanner,  and a little bitty one that
seems to be some kind of a "photo" scanner?  Got a USR modem,  I
think it's a 56K sportster.  And a couple of other things that I'm
wondering about,  maybe you guys can shed some light on them.

One is a little box,  with wall-wart,  labeled H-P "JetDirect EX
Plus" which seems to have a DB25 on the back (labeled
"printer"),  a BNC connector,  and a RJ45 connector -- I'm
guessing this is something that lets you connect a printer directly to a
LAN?  Some sort of a sticker on the top giving an IP address of
192.168.7.3,  I wonder if it's possible to change that?

Then there's a 3Com "OfficeConnect 56K Lan Modem",  no wall wart
with it or at least not attached,  but I got several in the pile and could
probably find one to work.  Two phone jacks and four RJ45 connectors on the
back and I'm wondering if I could use this as just a hub,  maybe.

Another gizmo sort of reminds me of the charger stand for a cell phone, 
the label says "SUPRA eSYNC Cradle".  There's a pair of phone
jacks on the bottom, a wire coming out with both a DB9 and a coaxial power
connector on it,  and some sort of a cradle with a row of gold-colored
contacts on it,  along with a button on the front.  The bag contains a
phone wire and a wall wart still in a box and a DB9 to DB25 adapter. 
Anybody know what's supposed to plug in here?

That little baby scanner is labeled "PRTEC SCANROM 4E / Photo" on
the nameplate,  and has an un-labeled wall wart connector for power,  and a
pair of DB25 connectors marked "computer" and "printer"
so I guess that's parallel interfaced.

The big flatbed scanner is interesting too,  it has both 50-pin and 25-pin
SCSI connectors on the back,  and a DB15 (mini,  like VGA) connector that
says something about "transparency",  presumably for some sort of
an accessory that I don't have.  It's a "Relisys",  a brand I'm
not familiar with offhand.

Any of you guys familiar with this sort of stuff?
