I was buying the Quadras just for the hard drive, I didn't realize there was an alternative. My Mac doesn't run the CNC but it is used to program and generate the G code which my machines use. There are much newer versions of programming software but I'm lazy and cheap! I will snap some pics and post them if I can figure how to do so. I may ask for some detailed help with this alternative drive you were mentioning. Maybe someone can find an Ebay auction with the appropriate equipment? Thanks for the help.
