Running TOPS-20 V4.1 under SIMH
From Computer History Wiki
The tape image can be downloaded from here: http://pdp-10.trailing-edge.com/tapes/bb-d867e-bm_tops20_v41_2020_instl.tap.bz2
Naturally you'll need the PDP-10 emulator from SIMH. You can download pre-compiled binaries from the sourceforge page: http://sourceforge.net/projects/simh/
With SIMH 3.8-0 I'm using the followinng as my install.ini unlike the following example from 2001...
set cpu tops-20 d wru 006 att tu i.tap set rp rp06 att rp t20.dsk boot tu

I've gotten all the way through a TOPS-20 V4.1 installation on simh,
but not without some caveats.
To start with, this log is produced with the next version of the
simulator, which includes logging. It also includes a shortcut for
dealing with the TOPS-20 V4.1 boot problem:
sim> set cpu tops20v41
catches the bad WRCSTM in the boot process. To do this by hand,
sim> d break 7
sim> BOOT TU or RP
Breakpoint at PC: 000007
sim> d 40127 770000000000
sim> c
The first part of the installation (up to the reboot) works just as
stated in the manuals. After the reboot, things aren't so clean:
------
sim> log t20.txt
Logging to file "t20.txt"
sim> d wru 006
sim> att tu c:\temp\tops20_v41_i.tap
sim> set rp rp06
sim> set cpu t20V41
sim> att rp t20.dsk
sim> boot tu
