[Simh] Interdata OS/32 - adding disks

[Davis Johnson]

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.
