* VIDEO: Fix bug: vid_ready can be used uninitialized.

* PDP11: Fix NG SET TYPE.
The sense of MATCH_CMD is reversed.

There should be a separate state for each of the eight displays.

Simulators built with DONT_USE_INTERNAL_ROM defined will not have hte
binary of the needed ROM or boot components build into the simulator
binaries. However, they will automatically and transparently fetch the
neeeded ROM or boot code from the web when these binary files aren't
available locally.
Some potential packaging platforms do not want to package/distribute
simh simulators which have build-in binary code (ROM images or other
boot code) which may have unknown copyright status. Historically Linux
distributed prebuild simulators but left it to a simulator user to reach out
on the web to pick up these needed pieces to actually use the simulator(s).
This addition allows the default simulator builds to include the needed
binary components built into the simulator(s). In addition, it also
allows simlators to be built with DONT_USE_INTERNAL_ROM defined and thus
not to contain the material with potentially questionalble providence,
but to transparently reach out to the web to fetch the needed component(s)
when they are needed without any effort on the part of the simulator user.
- Plan is to avoid "#ifdef DONT_USE_INTERNAL_ROM" in simulator code
and handle builtin or external files in SCP facilities
- Export ROM checksum value and source file path to allow for transparent
dynamic ROM location at run time.
- Update README to describe differences with open-simh
- Allow SET NOAUTOSIZE and SET AUTOSIZE
- Document deprecation and possibly non functionality of MinGW
Windows build support
- When dependencies needed for the specified build target(s) are not
all available, display explicitly what is package(s) are missing for the
current platform's package manager. Ask if the build should proceed
or if the missing pieces should be installed first. If the user wants to
install the missing package(s) first, then show them precicely what
commands are needed for that package manager on that platform.
If the platform is macOS and the package manager is HomeBrew, then
automatically install missing packages and perform the initially desired
build. All other package managers require root access, so the commands
the user needs to enter to install the missing packages and to restart the
build are displayed the build exits.
- Explicit support provided for
1) HomeBrew and MacPorts on macOS,
2) apt AND yum on various Linux distributions
3) pkgin on NetBSD
for Debian and
The BESM6 makefile build has always allowed a makefile argument FONTFILE=.
That option still exists and will change the default font file.
Also extend the default font file names to include one which is found on
NetBSD.
Compiled in support is preferred over dlopen efforts with a fallback to
printf/fgets when neither is available at compile and runtime.
All platforms support file path expansion on command entry of tab characters
- Leverage libedit which is minimal libreadline with BSD license
- Wineditline on Windows which is also a libreadline equivalent with
a BSD license
Both are dynamically loaded on startup if they're available on
the host.
- Avoid explicit search for font file (which is now done at runtime
activation of the display panel)
- Retain ability for FONTFILE to be explicitly specified on the make command
- Remove legacy support for SDL prior to SDL2
- Add support to dynamically locate a useful truetype font at panel startup
- Still support compile time provided font via FONTFILE
There are a lot of niggling fixes, mostly for incompatibility issues
found by Walter Mueller. Working out the 11/70 behavior is still not
fully done, but it's a lot better than it was, and it passes more of the
11/70 MMU diagnostic.
- Floating point. Now model sensitive in treating MMR1, for 2.11 BSD.
- MMR1 now tracks PC changes on 11/44, 11/45, 11/70, and J11 -(PC) and @-(PC).
- MMR1 is cleared at start of trap sequence on 11/45, 11/70.
- Red stack abort occurs before memory writes on 11/45, 11/70 (no other model has them).
