Apple IIc Plus System Disks?

[Your name <bogus@fake.com>]

Hello, I recently acquired an Apple IIc Plus computer, monitor and stand 
all in the original boxes. There is a joystick, but no mouse. Everything's 
hooked up and working, but I have no disks. It's been so many yeas since 
I've used something this ancient. I'm 42 and have been using computers 
since the mid-80s, but can't recall what's needed to get any use out of 
this. Guess I need to wrap my head around the idea of a system where each 
program you use requires disks that be loaded. My question is where to 
begin? Can anything be done without disks? What commands can be used? What 
is a good resource for the beginner with this system? Any tips or pointers 
are appreciated. Thanks, Gary

P.S. I have a whole box of old Mac software from a system I briefly had 
years ago. Can any of that be used?
