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
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
- 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
- General cleanup of codebase
- Fixed condition codes m6800.c from Roberto Sancho Villa
- Add additional FDC lfd-400 from Roberto Sancho Villa
- Add additional OS's (FLEX 1.0, FDOS 1.0, DOS68, MiniDOS, and MiniDOS-MPX)
to software support
- Add additional disk formats to software support dc-4.c from Roberto
Sancho Villa
- Add CPU history
- Fix LOAD/DUMP to support binary and hex
- Fix fprintf_sym to disassemble 6800 code correctly
- Add EXAMINE/DEPOSIT to CPU Memory
- Fixed disasm to space the register
- Add SET_FLAG(IF) to IRQ – fixed error in handling IRQ from
Roberto Sancho Villa
These devices start disabled and will be that way in essentially all
working systems, but there apparently was a DECnet Phase V
support for this device, so it is added to all systems. The DPV
should now be readily testable.
As mentioned in #1152. That PR will fix the DUP device.
At this time:
- The ZAP command exists to remove meta data from containers that
have it. Container files processed by the ZAP command will generally
be restored to the size it was before the addition of the meta data
and the file time stamps will be unchanged.
- Newly created containers get meta data.
- At attach time, containers that don't have meta data, but have
recognized file systems that fit within the drive it is being
attached to get meta data added without changing the file timestamps.
- Containers that don't have meta data and don't have a recognized
file system that is <= the drive size are attached without comment
and without adding meta data as long as the drive is NOT set to
autosize (controllers that support multiple drive types all default to
autosize, which can explicitly be disabled on a drive by drive basis).
- Containers that don't have meta data which are > the drive size can
only be attached read only.
- Containers with meta data can not be attached to a different
controller at all if the container size is smaller than the drive on the
other controller.
- Containers that have meta data can be freely be attached to the
controller that they were attached to when they got the meta data.
If a file system is detected, it will be reported. Otherwise if no
recognized file system is found, the attach will be silent. File
system detection reporting can be suppressed with -Q on the attach
command.
- Containers with meta data can only be attached read only to a different
controller if the container is larger than the drive it is being
attached to.
In the future:
- In general, containers with meta data (or recognized file systems)
will be attachable to MSCP and SCSI controllers, as long as reasonable
sector sizes and file system not requiring interleaving have been found.
- Containers without meta data will only be attachable if autosize
is disabled and the container is <= the size of the drive.
- Explicitly setting a drive type on a unit will implicitly disable
autosizing. If a user wants to set the default drive for a unit
and still allow autosizing they must explicitly set the unit to
autosize after setting the drive type.
Relevant to: #1065, #1059, #1094, #1100, #1118, #1117
- This change introduces a full refactor of the interrupt subsystem
for the system board (SBD) and the I/O bus (CIO). Interrupt decode
should now be significantly faster, and not require an expensive
calculation on every step.
- The TIMER device has been split into Rev 2 and Rev 3
implementations.
- The optional 3B2/400 Debug Monitor ROMs can now be booted by passing
the "DEMON" argument to the 3B2/400 simulator BOOT command. Any
of the following will cause the Debug Monitor ROM to be booted
instead of the standard 3B2/400 ROM:
sim> BOOT DEMON
sim> BOOT CPU DEMON
sim> BOOT DEMON CPU
This change introduces initial support for the AT&T 3B2 Rev 3 platform, based
around the WE32200 CPU with up to 64MB of RAM and SCSI disk and tape support.
This simulator is experimental and not yet supported. It will not be built by
default, but can be built with:
make 3b2-600
Or by using the 3B2-600 Windows Visual Studio project.
This change lays the groundwork for adding support for Rev 3 3B2 models,
which includes the Model 500, Model 600, and Model 1000.
Rather than use the fixed strings "400" and "1000" in file names, the
strings "rev2" and "rev3" will be used, which allows greater flexibility
to implement various system configurations more easily.
Additionally, this change adds a copy of the Debug Monitor (DEMON) ROM
image for the Rev 2 board, to be used soon in a later checkin.
