Hi All,
All my 8" SSDD /SSSDdisks are non formatted, which was the reason for my
initial troubles.
Nevertheless, my IBM System /23 (Type 5324) can format disks in three
different formats:
_1. IBM System /23 Format_
512 Bytes per Sector
Possible Disk: SSSD, SSDD, DSDD
_2. Standard Format_
128 Bytes per Sector
Possible Disk: SSSD, SSDD
_3. H- Format_
258 Bytes per Sector
Possible Disk: DSDD
_So option 2_ was the right one, also when nothing in the docs point to
the IBM 3740 format.
After booting the System/23 with the inserted maintenance Disk VOL002
the formatter program can be started with the following command: link
prepare
By now I have 20 RX02 Disks formatted, and was also able to create a
bootable RT11 Disk via my running RT11 installation on my RC25.
It is RT-11SJ (S) V04.00I ...
>>>
.FORMAT DY1:
DY1:/FORMAT-Are you sure?Y
?FORMAT-I-Formatting complete
<<<
>>>
.INIT/BAD DY1:
DY1:/Initialize; Are you sure? Y
?DUP-I-No bad blocks detected DY1:
<<<
Next step would be to install RT11 on my SCSI Disk, which is presented
through a Dilog SU726A as MSCP Device 0 (Address 160340 (will be 1760340
on my PDP-11/84)) to the system.
Disk is an DEC RZ22 and was also formatted and mapped, through the Dilog
"BIOS" (Jumper J14 in to boot Maintenance Address ... and @175000g
followed by FT)
Now it looks like I need the SU726A manual, as I have no clue as which
device RT11 should recognize the Dilog, I assume DU0: but RT11 doesn't
load the Device.

Any Hint how I get RT11 load the correct device so that I can format and
init the SCSI Disk?
Is maybe Someone here with an Manual of the Dilog? A SU723 could be also
helpful, ... .
Many Greetings
