microRSX-11 RX50 distribution

microRSX-11 is a expanded subset of RSX-11/M plus and was targetted at the microPDP-11 family of machines. Here is an archive of a distribution set of RX50 floppies I was recently given:

RT-11 RX50 Disk Images

In my missing to archive all software I have for my PDP-11, I’ve spent some time working through my RX50 disks. Here are the results of my labours

I archived them using John Wilsons excellent PUTR utility using a PC fitted with a 5.25″ floppy drive (as drive B:). Here is the process I used:

  • Start up PUTR
  • Mount the RX50 in foreign mode with:MOUNT B: /FOREIGN /RX50
  • Then for each floppy:COPY/DEV/FILE B: [imagename]

Here are the initial set of disk images I have created. I’ve not had a chance to look at them in detail, but there looks like there is plenty of stuff that is of interested to the general community:

Software Archiving

One of my main fears with my collection is loosing software over time as disks slowly decay. DEC media has proven amazingly resilient with many of my disks well over 30 years old. The reality is though that they won’t last forever and so I’ve decided now is the time to start a program of archiving them all to modern media.

I have the following to work my way through:

  • 40 RL02 packs
  • 24 RL01 packs
  • ~250 RX01 and RX02 floppies
  • ~100 RX50s
  • 24 TU56 tapes
  • ~100 TU58 tapes
  • 28 RK05 packs

Software wise, these will yield a mixture of XXDP, RT-11, RSX-11/M, RSX-11/M PLUS, and Unix software. As I complete them I will put any useful finds online to download for others to use.
