Dilog SU723A

[shadoooo]

Hello,
I just received from a friend a Dilog SU723A, but I don't find any 
documentation about it.
The board is rev.D and has two 50 pin connectors on top... which one 
should be used?
 From a quick look at the ICs on the PCB, I suspect one connector is for 
single ended, the other for differential SCSI,
but I'm not sure about it...
Anybody has some info / manual / other ROM dumps? My ROM image is 
available if somebody is interested on it.
As I suspect that the same board could support also SU726A, if would be 
nice if somebody has ROMs and/or PLA
dumps, could be interesting in being able to switch between features.
Thanks

Andrea
