We're talking about the installation you did from tape to RL, right? In
which case, the same tape can be used to install to RK. Really.
If you look at the tape, it looks like this:

So when you install, you start by restoring the saveset that is for your
type of disk, so you get a bootable system. And then you boot that,
which brings in all the rest, which is the same no matter which disk.

Excellent! The tape distribution is the only one that exists. It's meant
for all different types of machines and disks.
Hey
folks. Does anyone have images of the RSX-11M v4.8 RK06/RK07
kit? I have the RL kit, but I would like to have the RK06/RK07 kit.
Not sure exactly what you are looking for here. The distribution as
such makes no difference. If you have it on tape, it installs on any
type of disk. So are you
looking for a distribution that was on disk in the first
place?
Do you actually have a machine with RK06/RK07, which really makes it
absolutely necessary to have that media? In which case, you also need
someone to send you the actual disk packs? That might be a scary
proposal...
LSSM has several machines with RK07s, and I have one at home. We
have a great many RK07 disk packs. (like 40 or 50) If you have it
on RL, then if you can just get things up and running,
you can certainly build a new system that boots and runs from an RK06/07.
Yes, I've done that. But is it not the case that the sysgen command
procedures are different for the different disk distributions, due to
the way the files are broken up between volumes? The v4.8 RL
distribution specifically asks for the different volumes on DL1: and DL2:. For instance, on my first PDP-11 back in the 1980s,
I had an RSX-11M
v4.2 distribution tape that was "the RL kit" that restored onto five (or
was it four) RL01 packs, and you booted the first one and ran your
sysgen. But there was also the "big disk kit" which would run on any
single disk that was big enough.
It's five RL02 packs. Seven if you have RL01.
But no, there aren't different "kits".
The trick is that if you look in the various xxSYS savesets, you'll see
that each contains the basic stuff needed to just boot and get something
running, and then it have two files placed in [200,200].
TAPEKIT.CMD is just the procedure to copy from tape to the desired disk.
It's identical in all distributions, but it's needed on this saveset
because it is the script used to copy everything else over.
SGNTYP.CMD is probably of more interest to you. It is different for each
type, and is then used to inform SYSGEN about what target disks it
should gear towards.
So I'm under the impression that the different
kits, for different
types of disks, have different sysgen scripts for the way the files are
split amongst the volumes when restored from tape.
Nope. It's not done that way. Just a single file with some parameters to
make SYSGEN behave differently for different targets. And the tape kit
have them all.
SO, what makes it necessary to have that media is
the ability to run
a sysgen on a system running on an RK07 disk. I've created a 4.8 system
disk on RL02s and copied it to an RK07 pack, but now I'd like to do a
sysgen (adding hardware) and the sysgen scripts are asking for RL packs
to be mounted, and there are no RL02s on that system.
The *simplest* way of doing this correctly would be to have a machine
with RK07 and tape. Then you just follow the manual and install from
scratch. I guess that option is not viable.
Second would be to just have the tape available, and restore the DMSYS
to your RK07, and then run TAPEKIT to pull the rest down from the tape
to that disk.
Third is if you don't have access to tape, and just have the disks.
Copying all the files over, and replace [200,200]SGNTYP.CMD should be
enough, I think.
The SGNTYP.CMD for DMSYS looks like this:
.type dm:[200,200]sgntyp.cmd
.;
.; SGNTYP.CMD - Command file to define type of distribution kit
.;
.; Symbol definitions for RK06/RK07 distribution kit
.ENABLE GLOBAL
.SETF $RL
.SETF $2RK
.SETT $BGDSK
.SETT $RK06
The DLSYS SGNTYP.CMD looks like this (for reference):
.type dl:[200,200]sgntyp.cmd
.;
.; SGNTYP.CMD - Command file to define type of distribution kit
.;
.; Symbol definitions for RL01/RL02 distribution kit
.ENABLE GLOBAL
.SETT $RL
.SETF $2RK
.SETF $BGDSK
.SETF $RK06
I could add an RL02 to that system, temporarily,
but that wouldmake
a mess on the exhibit floor and we need to keep it in touring
configuration.
So you must have managed to make the disk bootable. And you have all the
bits and pieces there, it sounds like. So I suspect it's all about just
tweaking this file then.
