Saw a "PZ" in another post today - not on your list, trying to figure out what the heck a PZ machine is!
...How embarrassing, saw it was the first "P" on your list...I need lasik - BAD.
I checked and checked, just to ensure my "blindness" didn't gank me again, I do not see an abbreviation for Data East's Checkpoint, although I do see "CP" is already taken.
