So, does anybody have a M7810 they want to get rid of?
That is the PC11
interface. I don't know if that is a quad SPC board or a dual that needs
a M105 address board and an M7821 interrupt board. I think it needs the
extra boards.
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.
