I'm buying a Howtek 4500 drum scanner, which comes with a Powermac G3 workstation. I need to buy a monitor for the computer and calibrate it. I'm assuming it runs OS 9.x, with which my Spyder 3 is incompatible (as is the Spyder 2).

Any idea how to go about this?

You could upgrade the OS to 10.3 or 10.4, which would allow you to calibrate the monitor with what you have, and still allow you to run OS 9 programs to scan with. OSX 10.5 does not allow OS 9 programs to run.

What about calibrating the monitor on a different computer, then transferring the ICC profile over?

Check the ScanHiEnd Yahoo group. Someone there will know for sure.

Theoretically it should work. I don't know if the OS or software actually influence the colors on the monitor. If they don't, and I don't believe they do, then calibrating the same monitor on a different system should be fine as long as you properly import and apply the calibrated profile. Try it and see.

Thanks. The trick is figuring out how to identify the profile on one computer, then figuring out where to put it on the mac (I haven't used a mac in a LOOONG time).
