I didn't write the following, I'm just copying what I saved some time ago. It
may help you make use of RT11DV50.ISO.zip .

Subject: RT-11 distribution kits
From: Tony <[email protected]>

A few people have asked me about RT-11 distribution kits.
Earlier this year I posted the following to the alt.sys.pdp11 USENET newsgroup.
It may be of use to fellow PiDP11 owners... just merge the relevant disks
mentioned below into the /opt/pidp11/systems/rt11/boot.ini and boot the CD-ROM
(boot rq0) to make a distribution kit.

The following is my posting from alt.sys.pdp11 -
Just a note that Jerome Fine collected together a set of 24 RT-11 releases
(from V01-15 on a DECtape to V05.07 on an RL02 disk) in the form of a
consolidated CD-ROM image.
You can download the CD-ROM from
http://pdp-11.classiccmp.org/RT-11/dists/RT11DV50.ISO.zip
If you're using SIMH PDP11 you can access distributions from RT-11 partitions
on the CD-ROM using a SIMH ini file like -
; File rt11.ini for SIMH PDP11
set cpu 11/70, 4M
set cpu noidle
set throttle 10%
set dz disable
set hk disable
set tm disable
set rq enable
set rq0 cdrom
att rq0 RT11DV50.iso
; This is for copying an install disk to a RL02 disk image
; For older versions use DECtape (tc) or RK05 (rk)
set rl enable
set rl0 RL02
att rl0 RT11V57.dsk
boot rq0
; end of rt11.ini
Unzip the CD-ROM from the zip file into an empty directory with the above
rt11.ini and start SIMH PDP11
$ pdp11 rt11.ini
PDP-11 simulator V4.0-0 Current git commit id: 852c0bc1

/Users/tony/rt11/rt11.ini-7> att rq0 RT11DV50.iso
RQ0: 'RT11DV50.iso' Contains RT11 partitions
4 valid partitions, Type: V05, Sectors On Disk: 242406
/Users/tony/rt11/rt11.ini-13> att rl0 RT11V57.dsk
RL0: creating new file: RT11V57.dsk

.TYPE V5USER.TXT
[snip]
Each of the CD-ROM four partitions is available as device DU0:, DU1:, DU2: and
DU3:. There are two files on DU0: called README.1ST and README.2ND you should
examine for instructions and the layout of the CD-ROM.
For example, to make a bootable RL02 disk containing the RT-11 V05.07
installation kit, copy the disk-image file from DU2:RTV5RL.07 to the RL02 media
using -
.copy du2:rtv5rl.07 /file DL0: /dev
DL0:/Copy; Are you sure? Y
Output device is larger; Are you sure? Y
Now you have the installation disk on the RL02 in drive DL0:.
You can now perform an installation by booting this disk - but to do this
you should halt SIMH PDP11 and revise the start-up file to add another
RL02 device (as rl1), and boot from rl0. See the appropriate RT-11
installation guide for details (installation normally requires two additional
RL02 disks - one to make a backup of the installation disk, and the other
to make your working system disk).
The release notes are at -
http://www.bitsavers.org/pdf/dec/pdp11/rt11/v5.7_Oct98/AA-5286M-TC_RT-11_V5.7_Release_Notes_Oct98.pdf
and you can use this in conjunction with the V5.6 documentation at
