The 7x00's were dropped because they are heavily FET based... (BTW I LOVE my 7844 (true dual gun, but total overkill for anything I use it for)) I think the option you are thinking of is option 78, P11 CRT phosphor... If I recall the TM50x was dropped for the TM5000 series which basically added GPIB.. The 50x series had some REALLY useful modules (I think there was a double-wide function generator that still is pretty good (sine/square/triangle linear/log sweeps/am modulation etc).... -j.
