I have a such a beast which I have had to use under windows95. It is
some years old.

I have tried to use sane with it, but until now without success. Below
here is a description of what I have done. If somebody has succeeded in
getting such a scanner to work, I would like to know about it. Also I
have made serious mistakes in the procedure.

Here it goes...

I have installed sane 1.0.1 from a binary slackware package from
linuxmafia.org.

I have linux 2.2.13 with patches patch-2.2.13-ppSCSI-19990712 and
patch-2.2.13-ppdev4 from ftp://ftp.torque.net/tim. I installed the
patches without rebooting, but it shouldn't be necessary. I didn't see
any non-module changes in the patches. This means I do not run a
patched kernel, just the modules.

After that I did

# modprobe scsi_mod
# modprobe sg
# modprobe ppscsi
# modprobe onscsi

which gave me this in the system log:

Feb 13 18:09:46 loreto kernel: ppSCSI 0.91 (0.91) installed
Feb 13 18:09:50 loreto kernel: onscsi.1: onscsi 0.90 (0.91), OnSpec
90c26 at 0x378 mode 4 (EPP-32) dly 1 nice 0 sg 16

# cat /proc/scsi/onscsi/0
ident: onscsi 0.90 (0.91), OnSpec 90c26
base port: 0x378
mode: 4
mode name: EPP-32
delay: 1
nice: 0
verbose: 0
quiet: 0
tot_cmds: 48
tot_bytes: 1731
tot_errs: 0

so the SCSI adapter in the scanner is recognised, but

# cat /proc/scsi/scsi
Attached devices: none

The scanner is on scsi id=6, but it doesn't appear to be found, even
though the on-board scsi adapter is found.

Then scanimage fails too, because the device is not there.

Any help is appreciated. I am not very dependent on the scanner, but it
would be nice to have it under linux too.
