Time base for 7854: 7B85/80 or 7B92a

Martin Hodge

I have a newly acquired 7854 with one 7b85 time base. Is there any advantage to using a 7b85/7b80 pair over a single 7b92a in the right vertical slot?

Also I am looking for the reference card pocket thing (with cards) that goes on the top if anyone has a spare stored away. Contact me at mhodge[at]innocent(dot)com.
