The BOOT command for this device was not correctly documented in HELP
(appearing both supported and not) for PDP-11.
This change fixes the issue and syncs HELP output with the actual code
(by using the same #if conditional).
Adds 6850 DCD status latch to M2SIO devices.
Adds vector interrupt support to M2SIO devices.
Removes CTS inactive transmit disable from PMMI device.
Adds IMSAI-style programmed output to CPU/SIO devices.
SET CPU PO will display "PO: AREG" upon an "OUT 0FFH"
instruction.
SET CPU NOPO will disable the function (default).
Corrects problem with Mode 0 interrupts.
When the CPU receives an interrupt, it pushes the current
program counter on the stack. The current implementation
of Mode 0 was performing interrupt processing after fetching
the next opcode from RAM, which also increases the PC by 1.
This caused PC+1 to be pushed on the stack. The interrupt
processing is now done prior to fetching the next opcode,
preserving the correct program counter.
build_vstudio.bat converts the .vcproj files from Visual Studio 2008 to
.vcxproj when used with newer versions of Visual Studio and configures
it to build XP-compatible binaries using the v141_xp toolset. However,
this toolset is deprecated and may not be present when using Visual
Studio 2022. The script intends to edit the .vcxproj files only in the
case where it exists; however, due to a logic error it actually does
this unconditionally. This causes the build to fail on VS2022 when
the XP toolset is not present.
- Display Media-ID and Geometry info for all SHOW <unit> output when attached
- Use real drive Geometry info for all disk types
- Fix RA80 cylinders copied from RM80
- Fix RZ23 cylinders to reflect disk size
- Return correct cylinder info on MSCP error path
If the total sectors exceeds 127Gb this is not possible, but normal
simh disks are smaller and the largest user settable size via RAUSER
is just under 1Tb. The excessive size case (>127Gb) will have a CHS
of 0xFFFF10FF.
simh never cares about the CHS Disk Geometry value in the VHD footer
data structure, but other applications which do care about the CHS
value using the previously incorrect value as the capacity of the disk
even though the Current Size indicated in the footer may have been
larger.
- Only update simh/Development-Binaries on direct commits to the repo or
when PRs are actually merged.
- Add git lfs support to store 50+MB .tgz and .zip files.
Including maintaining Development-Binaries in the Appveyor cache
If running as root on most platforms or running on macOS with Home
Brew package manager, any missing packages for maximal simulator
functionality can be automatically installed during the build.
All options which are currently and previously described in the comments
as allowing {option-name}=1 to enable, are now enabled if {option-name}
is defined to be anything at all,
