Thanks Jon. My new R3000 is now loaded with flush carts, and I’m preparing to load the K7 carts after ridding the system of the OEM color. As you pointed out elsewhere, flushing the R3000 carts on a Mac is a challenge. So, I’ve purchased Parallels and Windows 7 to take advantage of the software that allows for a simpler flushing technique. My impression was that it was available on the 2Manuals.com site, but I’m unable to find it there. Could you or Dana provide a pointer?
