This looks cool, anyone try it?

Hi Sampsa,

How timely of you to observe this today.

Just last night I got code pieces from Matt Burke (the guy at
9track.net) to add VCB01 (QVSS) support to the simh codebase
for the MicroVAX I and MicroVAX II simulators.

I'm in the process of merging that code and adding the
necessary build mechanisms to the makefile as we speak.

This will be cleaned up and visible at
https://github.com/simh/simh in at most a couple of days....

For folks who build their own binaries, the latest github code
has a
VAXStation I and VAXStation II with the MonoChrome QVSS video
capabilities.

      sim> SET CPU MODEL=VAXSTATION

enables the video subsystem.

The VAXStation I has a limit of 4MB of RAM, the VAXStation II
has a limit of
16MB.

The makefile should just build the right thing if the
development support
for libSDL is installed on your platform.

Please provide bug reports and/or other feedback with issues
created at https://github.com/simh/simh/issues

There is a glitch in my scripts which build and package the
windows binaries
which is failing to build the simulators with video support, so
folks who count on the Windows Binaries will have to wait until I fix
this.

The Windows Binaries (including VAXStation I and VAXStation II) are
now available at:
https://github.com/simh/Win32-Development-Binaries

Download the latest zip file.

Hello!
Nice to know Mark. Any suggestions for implementing it on a
Raspberry Pi system w/ 512MB of memory?

I don't see any reason it wouldn't work as long as you've got the
right SDL
development pieces available.

I did get the code outside of your screen idea to build properly.

I'm not sure what this sentence means....   what does "code outside
of your
screen idea" mean?

Hello!
Oh sorry. I meant everything contained within the entire SIMH
retrieval except for the screen presentation method.

I think you are trying to say that all simulators except the MicroVAX I
(VAXStation I) and MicroVAX II (VAXStation II) built.   OK, that is expected.
Numerous folks are running the latest code on Raspberry Pi systems.   The
QVSS video on the MicroVAX I and MicroVAX II simulators   was just merged
into the code base last week.

If you can't get the MicroVAX I and MicroVAX II to build, I'm going to need
more information to help.     Please create an issue at
https://github.com/simh/simh/issues to record the problem and to contain
the details of chasing this down to a solution.

Please Include the output produced when you attempted to build these
simulators.

Thanks.

Hello!
That's just it Mark. After using the git pull <repository name> command to
pull everything into the source directory I chose, I then entered the created
one, examined everything briefly, and then entered the command make and
off it went.

I first made the BIN directory, and then did that. I did need to build the Altair
ones out of sequence however. Also the Nova one as well. I did not make
the ones for the older IBM machines or the other simulators that I wasn't
familiar with.

I found that the screen thing needed the SDL library and I wasn't ready to
massage the repositories that make up Debian on Raspberry Pi to find that
one so I let wait.

My only complaint is that when I ran the vax simulation to confirm that was
all working, it then told me that the IDLE function was disabled, that was
when I asked it about the devices.

Hi Gregg,

Nothing in the new codebase should have changed idle behavior (or availability) for any simulator.

Please provide the output of "SHOW VERSION" in the simulator which isn't behaving as you want.

The complete output produced when the simulator was built will also be useful.

Hello!
Coming up soon Mark. Several days ago I reconfigured my Raspberry Pi
to reflect using the most recent and updated release of Debian on the
thing, and containing the materials for our concerns. (That meant I
ran the regular tools for Debian to update things on it.)

And as it happens I also earlier did a fresh pull from your Git
repository and built everything fresh. Then the system told me that it
was as I related earlier.

I'm not sure if the mail list can support attachments so when I get
everything ready I'll create a new thread and provide details as to
where everything is available.
