David...
Thanks for the info on your web site.
I have an old intuous 2 with serial hookup that I love and have done many illustrations with since around '94 or '95.
The serial hookup is (as you implied) becoming a problem. Because I do some animation stuff and 3D stuff I am beefing up my system to a quad core and will go to Windows XP64 pro (I think you were using Macs... my condolences) to allow accessing up to 4-8 gigs of ram. The old tablet with serial connect is not compatible with that OS, (according to the Wacom site) - and, they say adaptors (serial to USB) are not "supported."
Was wondering if you have any experience with this or advice for work-arounds. I don't really look forward to getting a new tablet just for this reason.
Thanks for sharing your knowledge.
