Jerome Fine replies:

Somewhere there should still be a Sigma box that is about the
same size as a BA23 box.  It has a built-in 8" floppy (that can
also be double sided) that runs using the MSCP controller
and a hard drive, also using the MSCP controller.  The Qbus
backplane has at least 5 slots, maybe eight.  It runs RT-11.

I also have a number of Sigma ESDI hard disk drive controllers,
RQD11-EC that I use with Hitachi 5.25" hard disk drive of
600 MegaBytes.

Is this what you are looking for?

Sincerely yours,

Jerome Fine
