SMD cabling information / Symbolics know-nothings

Though a few system mfg's, notably DEC, still used them well into the '80's,
SMD was a thing of the past by '86 or so, since ESDI, IPI, SCSI, and even
ST506 were quite capable of surpassing its performance at a teensy fraction
of the cost at the controller, at the drive, and even in the cabling.

My CDC Lark drive seems to have gotten by on one 60-pin cable and one 26-pin
together with the KONAN controller I used. I do seem to remember the
typical SMD drive had four 60-pin connectors.

If you don't have any luck before then, check back with me on, say, Tuesday,
by which time I should have found my CDC spec for SMD.
