I?ve been trying to find *detailed* specifications (mainly detailed signal timings) for
the SMD disk interface but all I?ve found so far are the interface specifications for
individual disks (CDC, Fujitsu, etc). I?ve looked in the usual places (bitsavers mostly)
and haven?t found the spec itself. If anyone has any pointers, I?d appreciate it.
You've seen that the SMD spec (as of March 1981) is on Bitsavers?
pdf/cdc/discs/interface_specs/64712400_SMDCableSpec_Mar81.pdf
That doesn't cover later enhancements such as SMD-E.
