[comp.sys.apollo] daisy chained disks on old system

Hi, Does anybody know if (and how) you can daisy-chain disks (such as
PC or scuzzy (sp?) disks) off the controller in a DN 560 Winchester?

Thanx, Peter [ APM279L@VAXC.CC.MONASH.EDU.AU ]

The DN50 controller supports a single disk and a cartridge tape.
Some of the newer DN570/580/590 Turbos have a newer disk controller
which can handle either one ESDI disk and a cartridge tape or
two ESDI disks. I believe the early DN550/DN560's used a pre-ESDI
disk (maybe ST506 or something like that?).
