Unknown hardware...

[Rob Greene <nospam-greener@charter.net>]

I figure someone can help me out here.  I've got a bunch of hardware, some 
of which I really have no clue about.

1. Adaptive Firmware Card & associated I/O Box - I think this is for 
handicapped access??

2. Powerport DPP-002 (not a card, connects to GAME controller J21)

3. Quickie Controller (Vitesse Inc) - for a scanner? (but no scanner!)

4. Unknown card - does not use a slot, connects to J25 and Fan header. Was 
bolted to external slot just behind motherboard power connector.  The back 
has "(c) 1998 Roger Wagner Publishing".  Pictures at:

Any additional information would be appreciated.

I also have a Zip GSX (version 1.02) and an Echo II.  I assume there is 
software and information for both somewhere?  Is the Echo II needed in a 
GS?

Thanks!
