In a BA23, you use the same cables (a 2nd set obviously) for the
second DUA1: drive as the first drive. DON'T FORGET TO
SET THE DUA1: DRIVE AS DS4!!!!!!!!!!!!!!! The cables
are for a single MFM hard drive - standard PC type 34 pin
and 20 pin. The 34 pin cable is not daisy chained - there
are connectors for 2 * 34 pin cables and for 2 * 20 pin cables.
The 1st drive uses the bottom 34 pin connector and the left-side
20 pin connector. The 2nd drive uses the upper 34 connector and the
right-side 20 pint connector. The floppy uses the right-side 34 pin
connector. All directions are for a BA23 with the 19" direction
horizontal and the 8" direction vertical and the power switch on the
right-side.

The I/O distribution panel in a BA23 allows for 2 hard drives
and is intended for a dual RX50. I have never tried a dual RX33
in a BA23 on an RQDX3, but I presume it would work. I don't
know if the 2nd hard drive must be connected into the READY
and WRITE PROTECT buttons. I have heard that the 2nd
drive can float and that the default is READY and NOT
WRITE PROTECTED.

Sincerely yours,
