Help - Apple 3.5 Floppy Interface Card

[sirthomas@aol.comyadayada (SirThomas)]

I just bought a used IIe from a garage sale for the paltry sum of 15.00 (USD) 
Mostly because it had the RamWorks III & Grappler + cards.  Imagine my surprise
when it also contained a card marked, "Apple 3.5 Floppy Disk Drive Interface
Card."  But with a little researching through my old Open-Apple / A2 - Resource
mags, I discovered the cards that control the 800K UniDisks and 800K 3.5 Drive
and 1.44MB Super Drive were all named the same!  (The March 1992 edition which
also contains a letter from Beverly Cadieux for all those Texas II fans out
there.)

Ack!

How can one tell the difference by looking at the card?
