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 RodIs 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.
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. Rod
