You are correct: it was not SCSI (my apologies: it's been several years). I
remember now: it was a serial printer-like port (probably the RS232 you
mention). One thing for sure: it was *not* either USB or FireWire.
That was in early 2000, and we had to buy a Keyspan PCI adaptor (which
sometimes refused to work properly as if on a whim). Besides which, if one
wanted to use the Spectrolino separately from the Spectroscan, one needed to
use a power adaptor on top of all else, with its own additional wires and
connectors. One was hobbled by webs of connections and wires, some of which
came unstuck quite easily, requiring a reboot. It was a pain.

I don't own an iO myself, so what I know is from reading papers, sites and
other people's reports. The GretagMacbeth site makes mention of the iO's
ability to measure "transparent materials"
(<http://na.i1color.com/index.cfm/MenuItemID/133.htm>): I'm not sure whether
that is comparable to the small-aperture transparency function in the
Spectroscan T. (Can anyone please expand?)
If it's not, it would seem that it's a minus only if that specific function
is needed, though. Otherwise, are there any other truly significant
drawbacks that anyone can report?
