Exactly, the best solution is an RX50 distribution.
I have never seen one or a way of making one.
If you have a PDP-11 with an RX50 then you would need one.

Hi
I have built an 11/83 in a BA23 box.
It has a KDJ-11B, 2mB PMI memory, an RQDX3 with an RX50 attached,
Plus a CMD CQD 220A Disk controller with a digital RH18A 2Gig SCSI drive
attached.
Diag sees drive as RA82.
It boots and runs the diag disk and XXDP+ just fine.
I do not have install distributions for any of the 11/83 operating systems.
Daily driver system is a Windows 10 PC.
So how do I install an operating system?
Suggestions please.
Thanks
Rod
Is the PC old enough to still have PCI slots? If it is, one option would be
to pick up a cheap PCI SCSI controller, e.g. an AHA-2940, that you can use
to write disk images to a SCSI hard drive. Then use SIMH to create disk
images of an OS of interest that can then be dumped to the SCSI hard drive.
Or pick up a SCSI2SD device to use with the CMD CQD-220A instead of a SCSI
disk drive. Then copy disk images created using SIMH on the PC to an SD
card.
Is the CQD-220A a /TM version, or an /E version? If it's a /TM version you
could also pick up a cheap SCSI tape drive, and create installation tapes
for RSTS/E or 2.11BSD and boot from those to install on a SCSI hard drive.
I've done that a few times just for the heck of installing from tape. If
you have the /E version (or /T/M version) instead of the /TM version you
can do either MSCP or TMSCP, but not both at the same time.
For RT-11, that is small enough it wouldn't be difficult to install from
RX-50 disks, if you had a means to create disks from images.
