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.
