Has anyone tried any of these types of products?  That would be a nice 
way to add cards to a Qube, you can get twin adapters so you could try 
USB and firewire PCMCIA cards at the same time.  Or even if we'd be 
limited to using one at a time, it would still be easier to switch 
cards around since you would not have to open up the case.  Like the 
ELAN P111 <http://www.elandigitalsystems.com/adapter/p111.php>.

It looks like some support started in NetBSD 1.5?

Does it work OK on the Qube?

I just happen to have a bunch of PCMCIA cards hanging around gathering 
dust :) so the cost for one adapter to make a few of them work on the 
Qube would not be unreasonable to think about.

Thanks,

Brian
