RAMWorks 2 Chips

Hi folks...

I have a RAMWorks 2 card fully-populated with 1MB plus the 512K 
daughterboard.  I see from the AE catalog that it can hold up to 3MB.  
Is this on the main board, or 1MB mainboard+2MB daughterboard?  If it's 
the main board, does that mean I can just swap out my current chips for 
different ones to increase the memory?

Also, what's the difference between a RW2 and RW3?  Just the ability 
for the 3 to utilize the RGB daughterboard that the 2 can't?

Thanks!
