Spiffy. Mac OS 7.6 is pretty decent, although it can tax some of the lower '030s, especially if they're lacking in the RAM department.

My Dock Plus came with a key, which is often handy. I upgraded the hell out of it, too, with max'd VRAM and a 2GB hard drive. Make sure to stock lots of patience if you try to crack the Dock open, because it can be... unpleasant.
