Hi All,
I've been trying to install NetBSD 2.0 on the SimH VAX emulator, but the
install text shows up as control codes, rather than correctly spaced and
formatted.
You haven't done anything wrong -- SIMH doesn't provide any kind of
emulation other than straight TTY for its console window. I've run
Open VMS in Simh/VAX and have the same issue. You'll likely just have
to read around the control codes, and later use a telnet client to get
reasonable output, once the OS is installed.
When running simh under Linux/UNIX, wouldn't it work to put a real
VT100 (or clone or a proper emulator on an external PC), fire up a
getty, then run simh from that window? That way, the device external
to the CPU running simh would interpret the codes. That trick _does_
work for me running TOPS-20 under klh10. It was easier to do that
than fix or replace xterm which is _not_ VT100 compatible anymore. I
was unable to successfully run emacs on an xterm, but with a _real_
dumb terminal hung off the back of the machine, emacs ran perfectly.
What's puzzling to me is that that at least back in the 1980s, when
installing 4BSD, we used to use printing terminals like an LA36. If
the install procedure used ANSI sequences, for the most part, we'd
also see garbage. I guess by the time NetBSD 2.0 came around, it's
entirely possible that its developers assumed you were on a glass TTY,
but it's too "new" for me to have much experience with it.
I've installed NetBSD over a serial console on a lot of older
hardware. If I am not mistaken it prompts for a terminal type
very early in the install process, but I can't remember if I've
tried bare TTY to see how usable that was. I always do it from
minicom on another NetBSD box which has passable VT-100 emulation.
My first home online experience wa on a printing terminal, an old
1200 baud DecWriter that I hooked to an acoustic coupler to call
BBSes before I had a home computer of my own with a serial port.
'Reading the backscross' was as simple as pulling up the sheafs
of paper cascading behind the big DecWriter. Life has never
again been that simple.
