I remember frying a //c by plugging in an 800K external drive.
Hey! It fit!

  Early versions of the Apple //c didn't have
the support for 3.5" 
 drives. Mine is like that.  You can check which version of the //c 
 you have by going into Applesoft and doing a PRINT PEEK(64447).  If 
 it returns 255 then you have an original //c.  The tech ref shows 3 
 basic versions and their ID bytes as follows:

 Original //c : ID Byte = 255

 UniDisk //c : ID Byte = 0 
Mine returns 0, so this is the one.  It should support 3.5" drives,  though

 possibly not the one I've got.

  	Added 3.5" support
 	Increased ROM to 256K                          ^^^^ You've GOT to be kidding
me!

Unless it means "ROMs that will support 256K of RAM".
