: Interesting. According to the Apple //c Technical Reference manual (2nd ed)
: the following drive limits exist on //c computers:

: (p84-6)			Int	Ext

: //c	original	5.25	1x 5.25

: //c	Unidisk		5.25	1x u3.5		1x 5.25

: //c	memory exp	5.25	3x u3.5		1x 5.25

: //c+			a3.5	1x a3.5		3x u3.5		2x 5.25

: The //c mem exp has a maximum of 4 drives (int + ext).

My IIc only has to power the UniDisk and the external 5.25 as the CT100c 
Hard Drive has its own power supply. The IIc does not classify the 
external 5.25 drive in the '4' add-ons, due partly I guess, that it 
existed in the firmware before the UniDisk and memory expansion versions 
were available. I have 3 partitions on my HD + 1 UniDisk and 1 external 
5.25 and my system runs good but that's the limit for add-ons. If the HD 
did not have its own power, I doubt the IIc would be able to power 
everything properly.
