Connecting HP Scanjet IIP (2P) 25-pin SCSI To Modern PC?

How on earth do I connect this scanner?

I see there are two ports on the back, and both say scsi. One looks
like a regular 68-pin scsi centronics-style connector and the other
fits a 25-pin parallel port connector, which I thought might be a pass-
through for a dual printer-scanner configuration, but then again, hp's
site says the scanner shuts down to prevent damage when connected to a
parallel port.


If I can't connect this easily, I do have some old ISA scsi cards from
the local computer junkyard I can use, and have to use an older
computer.

Is it really worth the effort when a good modern flat-bed scanner is
$100 or so? If you decide to go the old PC route, make sure the SCSI
cards are the right kind - AFAIK there are / were several slightly
different kind of SCSI connectors.

Buy an Adaptec card on Ebay. Let me know what connectors is on the
card. I probably have a cable. 25 pin on the card is popular.

XP will do SCSI as will 98. See the adaptec site for lots of
information. Stay away for ISA. PCI is preferred.

The Centronics looking conector is probably a 50 pin conector. Very
popular with SCSI

SCSI only. Single-ended. 32-bit.
Scanner runs only in async mode.

The DB25 is also SCSI (a Mac convention at the time, and
not really SCSI-compliant).

I don't recall if the 2P had built-in termination or not.
It definitely does not have SCSI disconnect-reconnect,
and therefore needs a dedicated SCSI bus. Put it on
the same bus as a CDR, and you will burn coasters
during scans.

If you don't already own a PCI SCSI card, getting one,
plus a cable with suitable connectors at both ends, and
possibly a terminator, can easily cost more than you
would spend on a more capable USB color scanner.

Avoid. In particular avoid the original cards supplied with
the scanner. They don't support IRQ (trace isn't even
present at the edge connector), and simply do not work in
most post-2000 operating systems.

If you do have the parts, I can tell you that DeskScan II 2.9
does run under Windows XP. Preview window size seems
to have a size limit if your screen is 1600x1200 or higher.

The life of the CCFL bulb in the scanner is not infinite.
