Help IIgs How much RAM

[kuk@polaris.fnal.gov (kevin kuk)]

Hello,

I've look over the FAQ and could not find a answer to tell how much
RAM a IIgs has? 

A little back ground on my situation:
My sons kindergarten class had a IIgs donated last school year.
After asking if the children would get a chance to use it this year , I
found myself volunteering to get it running.:)

Inventory of the system:
 Apple II gs ROM version 01
 color monitor
 3 1/2 disk drive
 5 1/4 disk drive
 Apple IIgs Memory Expansion with 32 memory chips on it (I opened the cover
 and looked)
 
software:
 Tour disk of the Apple IIgs
 Reader Rabbit

The system will run the tour program and the Reader Rabbit program.
I see from the FAQ that I can get a copy of the system 6 GS/OS from
the Apple site but I don't know if I have enough RAM to make it work?

Thanks for any and all help,
Kevin Kuk
