Our local VAR (value-added reseller) offers free 3-hr intro classes one night per month. It's obviously for marketing and just barely skims the surface but if you've got somebody local doing the same, it would be a way to at least get a glimpse.
Granted, your software's much older and many features aren't present, but it might help you with some basic concepts of how to model parts and assemblies. It's a very different mind-set than with traditional CAD or drafting.
On the other hand, it's likely to frustrate you when you see what you don't have.
I feel for you. My boss is not much better than yours although he did ultimately agree to aquire the software. Now if I can only convince him to pop for some RAM I'll really be cruising.
