It doesn't jump out at me - the A009 status is device unavailable (a0)
device not responding on bus (09).
My current SIMH system is down at the moment. If you have configured and
attached the new disks like the existing one I don't know.
Your configuration may not be legal in the physical world.
The 40mb drive was an older oddball. I'm not as familiar with them. They
may use the same controller as the 2.5 and 5 mb drives.
The 67 & 256 mb disks were contemporaries. They were SMD drives from CDC
and everybody (including DEC) sold them.
There were two SMD controllers, older "MSM" and newer "IDC". The IDC
controller relaxed some of the restrictions on mixing drives in the same
string.
Try configuring multiple identical disks. I know that I've done that
with SIMH.

I tried adding a couple of large disks by creating a new configuration
file from OS32MTS1.SYS and changing the following lines:
41 DSC3:,FC,52,SELCH=F0,CONTR=FB * 40-MB DISK (REMOVEABLE)
42 DSC4:,FC,53,SELCH=F0,CONTR=FB * 67-MB DISK (REMOVEABLE)
43 DSC5:,FC,54,SELCH=F0,CONTR=FB *256-MB DISK (REMOVEABLE)
to
41 DSC3:,FD,54,SELCH=F0,CONTR=FB *256-MB DISK (REMOVEABLE)
42 DSC4:,FC,53,SELCH=F0,CONTR=FB * 67-MB DISK (REMOVEABLE)
43 DSC5:,FE,53,SELCH=F0,CONTR=FB * 67-MB DISK (REMOVEABLE)
The change is the device addresses and types in lines 41 and 43.
The sysgen went ok and when I load the new OS, "D D" shows DSC3 and
DSC5 on the new addresses.
However, when I try to initialize DSC5 I get:
sim> set dm1 msm80
sim> att dm1 dm1.dsk
sim> c

Any suggestions?
