If anyone on the list is aware of Sigma equipment still
in existence,

contact me. I am aware that Honeywell forcibly retired the systems as

contracts expired in the early 80s, and that this will be very rare if
it does
exist at all.
Thanks,

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
