I need information pertaining to future industry standards for shielded
SCSI connectors. 

We, at Intergraph, currently support 2 different types of shielded SCSI
connector:
	a)  Centronics-style 50-contact (0.085 inch spacing)... preferred
	b)  AMP              50-pin     (0.100 inch spacing)

The proposed SCSI-2 specification lists 2 shielded connector options
for the A cable:
	a)  AMP              high-density 50-pin     (0.050 inch spacing)
	b)  Centronics-style low-density  50-contact (0.085 inch spacing) 

I believe that ANSI X3T9.2 (SCSI Committee) members were supporting a
move to high-density connectors to fit the smaller physical dimensions
of the next generation computer products (especially personal
computers). 

Are manufacturers of SCSI products really planning to change to the
high-density connectors in the near future? Or, are they planning to
stay with the low-density connectors to remain compatible with existing
products?
