As an aside, the communcations protocol for the 9885

in any maula that I've seen....
Command and status words for the 9885 appear in Appendix A of the
"12732A/12733A Flexible Disc Subsystem Diagnostic Reference Manual" (12732-
90003 December 1977) for the HP 1000. The "HP 12732A/12733A Flexible Disc
Subsystem Operating and Service Manual" (12732-90005 October 1978) for the
1000 details the cabling between the CPU's parallel interfaces and the 9885
drives on page 2-7.
