Hi Gene,

It is not clear if you say you’re seeing the same behavior on 3.9 vs 4.0.

Please confirm.

Also your configuration file and the output of sim> SHOW VERSION on 4.0 will be 
useful.

The point of these questions is to determine if you’re having a simh issue or a 
rsts issue.

Subject: [Simh] PDP11 oddity with RSTS 9.6

Hello guys,
I have tried simh 3.9 and 4.0 and have this odd issue.
I got a copy of a built rsts on rpo6, and the copies of the .tap files used to 
gen this image.  it is v9.6.
If I boot the prebuilt hard drive image the system comes up just fine.
If I boot the tape and go through the sysgen process the hard drive image that 
is built has no lp0: device in the monitor, and the spooler fails during boot 
and keeps the rest of the start.com<http://start.com> script from running, 
making the system come up in a single user mode with job max at 2.
I've tried diferent processors (11/70 up to 11/94), LPT is enabled in simh, and 
I'm not sure what to try next.
If I boot the prebuilt image and do show devices _LP0: is present.
If I boot the sysgen'd image and do show devices, there is no _LP0:
anyone got any ideas?
