I've spent well over a week researching what profiling software was available for OS9 and here's what I've come up.
My research was concentrated solely on software for 'industry standart' i1Pro spectrophotometer.
I ignored anything that was ment for lesser devices - i.e. colorimeters, which might be dead/deteriorated by now anyway.
1. Monaco Systems - acquired by x-Rite, old software discontinued

c)

3.0.1 and
3.1 (!) (same as 2.03, display profiling only)
d)
Eye-One Share up to ver.

e)
ColorLab up to v.
2.8.12 (free, experimental, very sloooooow)
3.
basICColor - still active, but old software is not available for download
www.basiccolor.debasICColor Display v.
3.0 (features and quality unknown, v. 5.x.x for OSX seems to be good)
4.
Quato - makers of High-End Monitors and software, went belly-up in August 2013

2.5, maybe
2.5.4Software still downloadable from archive.org, but key number is needed to make it work. (Anyone?)
Version 3.8.x for OSX is, in my opinion, very good. In fact, I like it better than basICColor and i1Profiler.
P.S. I have #2 b, c, d and e.
