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.
