My z-158 is running one of the earliest Adaptec RLL controllers quite
happily.  This controller, and probably others, are not recognized
properly by the monitor ROM, so that no matter how I reboot --- straight
reboot or ROM-monitor command --- the machine always tries to go the
floppy drive before using the hard disk.  Since I never store floppies in
the floppy drive, this merely slows down the boot by a second or three
(out of 60 or so to get all the EMS, TSR, and other goodies loaded up).

The z-159 ROM is surely newer than mine, and may do a better job of
identifying non-Zenith controllers, but it really isn't a problem anyway.
I would expect an RLL controller to work fine.
