Re: IIc Questions

["Mark Cummings" <NOTfigjams@primus.com.au>]

probably didn't explain that too well... Apple made the "Apple 3.5 Drive"
AND the "Apple Unidisk 3.5".
The Unidisk 3.5 has the wider & thinner eject button and the LED is mostly
on the front, whereas the Apple 3.5 drive has the smaller eject button (with
a hole in it) an the LED is narrower and goes around the side more. Also the
Unidisk has the LED and Eject button positioned higher up.
does that make sense now?
