I'm selling my upgraded 7100 because we're moving, and we already have too many computers.
It's got a NuPower 246mhz G3 card with 1 megabyte of L2 cache running at 2/3 clock speed. The HD is 2 gigs, and it has 132 megabytes of ram. (It could be 136, but I'm not in right now to check it) An interesting thing about the 7100 is that is has both video in AND video out, something newer macs lack. The monitor is 16 inches (viewable) SVGA (800 x 600)and supports millions of colors.
It has a CD-ROM drive and a floppy drive.
I'm looking for offers in the range of $350.
Post here if interested.
