anyone running a macbook pro retina machine with both Snow Leopard and Yosemite 10.10.5?

I have alot of files written with AppleWorks 6, which SL handles w/o problem. Its much easier for me

to use than Pages . Would like to keep using that AW6 for awhile longer as it would be a hassle to

recreate so many documents in Pages. One solution I've considered is to format SSD and thus erase

Yosemite, then install Snow Leopard on the Retina machine, but I'm wondering if it's possible to have both

OS's installed on separate partitions and boot to one OR the other. Any advice or comments would be

appreciated. I know there are some brilliant apple computer genius's out there and if you know how to

instruct me to do what I'm describing, I'll reward you with some of the best Kona coffee you ever tasted!!
