Yes, the boot ROM includes instructions for the VT11 display processor.
Admittedly, I'm quite clueless when it comes to details about the PDP-11
and Unibus. The vt_fetch function in pdp11_vt.c does go through the I/O
map, but apparently that by i
Apparently, the GT40 does this. So... problems.
1. The original simulator I wrote didn't support DMA to IO space. Code
for this was added in V4, but the code conformed to the internal
simulator convention that all addresses are 22b wide. This is certainly
not the case for Unibus DMA devices; t

gad dyslexia sucks... the sentence was supposed to say: This is true for
all UNIX implementations, including the UNIX-like/work alikes from Idris,
Coherent, Sol, and Linux

Here is a project I found put together from the original programming notes.
It's not complete but it runs on Simh and gives you an idea of what it can
do.

Or SIMH -- which includes PDP-7 emulation, doesn't it? Certainly PDP-9, which
presumably could be tweaked if need be quite easily.

I don't think that is true since it predates the 1976 removal

I see some PDP-11 models went to console ODT mode when executing the
HALT instruction. This could also be added to SIMH, as an option.

Hello,
I'm running ITS on the PDP-10 simulator. ITS has a built-in
configuration for each DZ11 line. That includes speed, terminal type,
etc.
For example, the GT40 I mentioned in another thread was connected to one
particular line and some applications have built-in knowledge about
this.
