For those who have seen the ads for Sharp's JX100 color scanner, I have
some information that I received in the mail.
It is serial-port-based. Its largest scan area is 3.9" x 6.3" (A6 size).
It has a max resolution of 200dpi at 6 bits (though you can request either
1-bit or 8-bit output, the 8-bit output is only accurate to 6-bits). I
don't know how it stores color images, but it is 18-bit color ("262,144").
Scan times (at 115,200bps on the RS232C port) for the full 3.9 x 6.3:
1-bit b/w 40 sec
6-bit b/w 3 min
Color times are 3x these. Top serial speed is claimed to be 172Kbps, which,
if it does this on the Mac, would cut these times by 1/3.
The unit uses a CCD sensor; is powered by an AC adaptor; can scan an area
as small as .04" x .04"; can scale 50-400% in 10% increments; has Gamma
Correction; weighs 4.3lbs.
It is unclear whether color scanning is automatic, or whether any kind of
manual intervention (say slipping in color filters) is necessary.
The cost is $995, with "Chromoscan" software and cables included.

MacWorld, they had a guy who was showing a post-production JX100. The unit did the color passes itself without any manual filter changing. When I tried it, however, the color quality was not very good. The guy indicated, however, that they didnt do proper palette optimizing in software and it should be fixed in the release. Anybody know if they did? Myron
