..have repaired a HH725 Harddisk /TA7245BP was bad since a tantal Elko had
a short) and booted now RT11 V5.07 with the new now repaired 1/73 CPU.
Resorc /A give the following informations:
.resorc /a
RT-11XB (S) V05.07
Booted from DL0:RT11XB
Resident Monitor base is 111774 (37884.)
USR is set NOSWAP
TT is set NOQUIET
Indirect file abort level is ERROR
Indirect file nesting depth is 3
PDT 11/150 Processor
FP11 Hardware Floating Point Unit
Extended Instruction Set (EIS)
KT11 Memory Management Unit
Cache Memory
50 Cycle System Clock
Device I/O time-out support
Multi-terminal support
Hmm, is that normal that the CPU gets identified as PDT11/150?
Interestingly it finds an FP11 but the Socket is empty.
For an M8186 the output is more that what I've expected:
.resorc /a
RT-11XB (S) V05.07
Booted from DL0:RT11XB
Resident Monitor base is 111774 (37884.)
USR is set NOSWAP

I wonder what it looks for to produce that.

J-11 always has float support. Without the float chip, it's in CPU microcode; with
it, that chip offloads the float and it goes faster.

I suspect that somehow, somewhere you have managed
to include the RESORC.SAV file from V04.00 of RT-11
(which was released in 1980) or at least a version of RT-11
prior to V05.00 (which was released in 1983).
If I remember correctly, that version of RT-11 did not
include support for the PDP-11/73 CPU since I don't
think that any of the PDP-11/73 boards were released
until after 1980.
Furthermore, I just booted a standard distribution of
V05.07 of RT-11 using the standard RT11XM monitor
distributed by Mentec for V05.07 of RT-11. I ran
using a PDP-11/73 CPU (actually under Ersatz-11)
I then MOUNTed a DSK file which contained the V04.00
RT-11 distribution:
MOUNT LD0: DU0:RTV4RK.00/NOWR
RUN LD0:RESORC /Z
and the result that you displayed was essentially duplicated,
with about the only difference being the Resident Monitor
base address since RT11XM was being used.
If you type:
RUN SY:RESORC
and follow the command with 2 <RETURN>s, the version
of RESORC.SAV which is being used will be displayed.
It will probably say:
RESORC V4.00
If you can somehow find the version of RESORC.SAV
that is distributed with V05.07 of RT-11 and type:
RUN RESORC.SAV
The information for V05.07 is:
RESORC V05.21
Hopefully, the correct information will be displayed with
the version of RESORC.SAV which was distributed
with V05.07 of RT-11.
In case anyone else who is running RT-11 is reading this,
using RESORC.SAV from V04.00 while running any
version of RT-11 starting with V04.00 will produce the
same problem when a PDP-11/73 is used. I have not
checked what occurs with earlier versions of RESORC
and RT-11.
For an M8186 the output is more that what I've
expected:
.resorc /a
RT-11XB (S) V05.07

You are exactly right!
It displays V4.00.
I must take a look to my old SIMH installation since I wrote the
tapes from which I've installed the disk from there..
IMHO I've donloaded it with exactly that resorc.sav.
I'll try to find another one .. and a way to get it onto the disk finally.
As far as I remember I had an SIMH installation on my previous PC
and wrote tape files there that I copied to real tapes from which I finally
installed that RT11. (I have the disk contents of the previous PC archived
on tapes)
Thanks Jerome!
