I have one of the original 8-bit binary-only Logic's rattling around in the garage and I wish I had more time/skill/ideas with which to play with it. The last time I used it was when I was in the process of repairing an old Commodore PET and it was absolutely awesome for checking out the hunches I came up with while staring at the schematics. (My old oscilloscope doesn't have any memory features and has only two channels so it's less than great for checking out "When this line *and* that line are high then this line should be low" situations. I'm sure any old logic analyzer would do, but the Saleae was slick, easy to set up, and of course far cheaper than a new "real" logic analyzer.)

Really the only thing I could complain about is, yeah, even *one* more channel would have been nice. There were a couple situations where it would have been really handy to be able to watch, say, all 8 data lines on the 6502 and have one more signal to connect to a chip enable/rw signal.
