old external Apple drive

When my WD20AP unit is attached to an ADAPTEC AHA1542B under DOS and allowed to boot with the drive turned on, it "sees" and reports the presence of a device, WD-1006-something which it later reports it can't spin up. It looks like it belongs to the late Apple-II/early MAC period, being shaped and colored to match. (take the color info with a grain of salt, though, since I'm "chromatically challenged.") It's pretty clearly a SCSI device, else the SCSI controller (AHA1542B) would not be able to communicate with it via the SCSI-1<=>DB25 (Comonly used with Apple SCSI ports) adapter cable. I wouldn't bet on a healthy result attaching the device to anything not SCSI. It's possible that my unit had a dead drive in it, at least if there's a bridge controller, which I'd readily believe, but if there's a bridge, it probably wants to be set up, i.e. told what sort of drive it's got, which has to happen from the outside if it can't readily read the drive info from the drive itself, in most cases. Now, a couple of other Apple type external drives with which I've experimented have had customed firmware that prevents the bridge controller from behaving as similar models would behave, possibly requiring that they see the Apple setup routines before doing anything. I'm not at all certain about that.
