As I continue building my MDD setup for long-term OS9 use, I'd like some recommendations for expansion cards.

Requirements:

1) Useful

2) Compatible with OS9

Would a SATA card do? How about USB 2.0? A SCSI card? Is there a card that will allow VBR floppy drive use?

I've never used expansion cards before. I don't know what's out there, I don't know what plays nice with OS9, and I don't know what will be most useful.

I'm open to any and all suggestions.

Thanks in advance.
