Ran one for years with two RD54s, DEQNA, 13mb, DHV11, TK50 controller,
LPV11, RQDX3. The description is so you know it was a full box. Insure
the internal power cable is good and the ECOd one.

I agree on the cable. It is amazing how it will smoke. I just have never
been willing to try putting 2 drives in. ( I have several BA123's for test
beds and operating systems) I find them to be much easier on the hands.

OK, I've heard all the stories about this cable. I suspect I have
a "bad" one in a BA23. How do I get a "good" one? Is there still
a DEC part I can order? Or, do I have to go the the local wrecking
yard and find one?
Thanks,
Dave

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,
