OK, so it's not ten years old and therefore it isn't a classic.
But I use my ScanJet 3C to scan documents *about* classic computers,
and make them available on the web. For instance, the PDP-10 documentation
at
http://www.36bit.org/
So if anyone has an ADF (sheet feeder) that they're willing to sell,
please let me know. The one HP intended for it was the C2525A, but
I think the C2525B (for ScanJet 4C) and C6265A (for ScanJet 6100C)
will work as well. Also, the C1751A (for the ScanJet IIc & IIcx) might
work.
Thanks!
