Note: To avoid potential breakage of existing PDP11 configurations in
the wild, which may expect RP on RHA, TU on RHB and RS on RHC,
RPB is connected to RHD Massbus adapter.
- More robust recovery when Massbus configuration errors occur
- More complete RH{A,B,C,D} help
Removed TQ (TMSCP), TS (TSV11) and VH (DHV11) devices from this
simulator since these devices were never supported in release MicroVAX I
configurations.
Lacking a scatter/gather map, DMA devices needed to be written to
perform DMA into contigous buffers in low memory and then copy data
to user space buffers. The MSCP protocol devices had specific support to
do scatter/gather transfers as part of the protocol. The RL01/RL02 device
driver was modified to perform the appropriate buffer moves most likely
to prove the customer option to adjust their drivers actually worked. In
any case, boot support for RL01/RL02 disks does not exist.
This PR adds support for the Processor Technology VDM-1 display adapter and Sol-20 computer system. The VDM-1 was integrated into the Sol-20 but has been separated out into its own device.
This PR adds the following devices to the AltairZ80 simulator:
VDM1 - Processor Technology VDM-1 display adapter
SOL20 - Processor Technology SOL20 with SOLOS ROMs
SOL20K - SOL20 Keyboard (callback from VDM1)
SOL20T - SOL20 Tape (reads/writes cassette file images)
SOL20S - SOL20 Serial Port (TMXR capable)
SOL20P - SOL20 Printer Port (TMXR capable)
When converting to a newer Visual Studio version, a new solution file is
created named simh-'vsversion'.sln so that we don't modify any files
managed by git. The resulting converted solution file will be automatically
used when build_vstudio.bat is subsequently run and that solution can be
opened directly by the Visual Studio IDE.
- Pre-Pre-Build-Event.cmd now dynamically determines the available
compiler version along with any alternate toolset which may be part
of the build environment and makes the appropriate windows-build
library support available for linking.
- build_vstudio.bat now supports VS2022 and will dynamically adjust
the converted VS2008 project files to leverage any available XP build
support which might be installed so that the generated executables
will support all versions of Windows from XP onward. The VS2008
generated executables automatically support all versions of Windows
from XP onward.
Visual Studio defaults to disable the ability to redirect stdout and stderr
for the cl.exe program during a build. This change allows us to capture,
record and display the compiler version.
This commit introduces dozens of changes to make the 3B2-700 simulator
fully functional and ready for wider use. In addition to 3B2-700
availability, this commit includes a tremendous amount of refactoring
of the 3B2-400 and common code to make the project structure easier to
maintain and reason about.
* AltairZ80: SS1: Fix disable after reset.
The CompuPro System Support 1 could not be disabled after enabled and
used due to timers causing it to be busy. Reset properly so that "set
ss1 disabled" works after reset.
* AltairZ80: wd179x: Properly reset 179x state.
* AltairZ80: M68K: Fix compile with VS2008.
* Musashi: Fix compilation with Visual Studio 2008.
* AltairZ80: M68K: Resolve warnings in softfloat.
* AltairZ80: Add headers to .vcproj
