I own 3 IIc+'s.  One I use daily.  One I got for parts.  One I got just 
'cuz I couldn't resist the price.  Yes, it runs at about 4 MHz, faster 
than an unaccelerated GS.

Another advantage here is that you can use "dumb" drives, like almost any 
Mac 3.5 drive.  You are not tied to the discontinued Unidisk 3.5.

Applied engineering made the Ram Express and Ram Express II.  It is a 
slinky ram card that maps to slot 4 drive 1.  The Ram Express II uses 
256kx4 chips up to a total of 1 Meg and has a clock.
