RT-11 with dual MSCP controllers

19 Jun 2014

Does anyone have RT-11 actually running with two MSCP disk controllers?

My 11/83 has a CMD CQD220A/TM at 172150, and an RQDX3 at 160334.  The rqdx3 has an rx33
floppy drive, and is set for starting LUN 4. 

No matter what I do, RT-11 simply won't see the floppy. I've run sysgen, specified
the addresses of both controllers, nothing works.

So, if anyone actually has a running system with dual controllers, I would love to see the
SET DEVICE stuff that makes it work.

Thanks for any advice.
