I just figured out the problem.
Not all CAMAC crates have the +/- 12 V pin assignment. The status byte, among other things, uses an auxilary -6 V which is supplied by the -12 V pin. The -6 V can be found at pin Y1, or the fourth pin up on the left side of the GPIB slots.
The crate that I have does NOT have 12 V pins. Therefore, the status byte, and things like the Lecroy 2373 Memory Lookup unit DO NOT work.
Being the hack that I am, I wired -6 V of power into my crate, and now everything works. It looks a little dangerous, but it works.
