I was just going to suggest the same thing, but I see you (Tez) are going the FDADAP route; more convenient for sure.

But the majority of the 34- and 50-pin signals actually line up 1 to 1 when aligned pin 34 to pin 50; as a matter of fact I have a system that uses the same 34-pin  cable to connect to both, with just a jumper or two to select 5 or 8" (the index signal is one IIRC).
