That chart should have the frequencies at the top over each speed group. I 
think it was the DL11-A,B,C,D printset I was looking at that listed the 
frequencies.

Yeah, I tried Jan Crystals, they said they couldn't sell me a new crystal 
unless I knew something called the "load factor" of the existing crystal. 
That tidbit I don't see in the documentation. They also wanted $20 each, and 
that seemed a bit steep.

At some point in the future I'd like to upgrade the crystals on both my 
M7800's. However, in the mean time I have found a M7856 which makes for a 
much more usable console speed :)
