[sane-devel] SANE driver for NEC Petiscan scanner

[Allan Kaplan]

Greetings again,

Here is the progress I have made:

The sketchy results of sane-find-scanner -v -v follow.

NEC drivers for Win 95, 98, ME, 2000 (apparently), and MacOS 9.x (they say
X, but not true) are at

<http://www.nevt.co.jp/scan/download/800u3.html>.

The filenames are English even though this is a Japanese page.  The files
are the "8u3" files.  At the bottom of the page is a link to
"MultiReaderPetiScan800U2" which is the previous version of the PC drivers.

As far as I can tell, without further digging into the guts of the scanner,
there are two chips which say

JIC (?)
ES52099S
9919-LHIJ
I was not able to find data on this chip.

And

Winbond
W24512AJ-15
919SA290732601CE
Chip specs: 
<http://www.chipdocs.com/pndecoder/datasheets/WBOND/W24512AJ-15.html>

It occurred to me that this scanner will run off another computer I have
access to, but only in MacOS9.  Might there more data that I can access from
a computer that will actually run the scanner, versus this laptop with which
I want to ultimately run the scanner, but only uses MacOSX?

Thanks everyone for your help.  Please advise me on the next step I can take
in this project.

Allan
