 that's a half-height ISA card with the designation SCB5 Junior.  It's
 got a mini-din at the backpanel, though it's definitely not the keyed
 sort used by a mouse or keyboard.  I've got to admit, I'm puzzled. 
Do you mean half-height? or half length?
Is there any circuitry or chips on the board?
That might help to narrow the choices
        bus mouse
        scanner (particularly hand scanner)
        graphics tablet
        camera
        sound
        . . .
  The PC, BTW, was a 150 MHz Packard Bell
"Platinum" with a 5 GB WD
 drive and a 56x CDROM, along with the "usual" sound and modem boards
 and the usual built-ins.  It had no keyboard or mouse, and therefore
 cost only $1.99.  I've already established that the drives work, and
 the machine, which has 48MB of 72-pin DRAM, also seems to run without
 a hitch.  Unfortunately, the OS will have to be reinstalled, since it
 was passworded. 
WHICH OS?
NT has real passwords, but is probably crackable.
9x passwords are NOT even intended to keep you out, and you can create a
new "login" without having to crack the old one.
What kind of partition does it have?
