I am pretty sure both forms existed (although IIRC the M7810 is the 
quad-height card). I have one of those (sorry, it's in use...), but I 
think the printset I have is for the dual-height board that goes with an 
M105 and M7821. 

>From what I remember, the quad-height board is really just the 
dual-height one + an M105 + an M7821 (or similar) on one PCB. The 3 parts 
are not connected together on the PCB (maybe pwoer and ground are, the 
logic signals aren;t), they use the backplane wires that are used when 
you have the 3 separate PCBs.
