Historically on *nix platforms ifconfig was used to find the host system's
interface MAC address. This isn't always available on all systems since
it's being replaced by the ip command. We now only invoke commands
that exist.
- 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
The actual contents of the input ROM binary files and the contents of the
created arrays are unchanged.
Multiple ROM image include files can be included in the same source module
without the need for any #undef BOOT_CODE_SIZE, etc.
When multiple ROM images are included by the same source module,
#define variables with names BOOT_CODE_SIZE_n, BOOT_CODE_FILENAME_n
and BOOT_CODE_ARRAY_n will be defined.
- A prompt answer which exactly matches a topic name is given
preference over the potential ambiguity of other topics which start
with the same text.
- Prompt with the parent topic's prompt when a just displayed subtopic
has no subtopics.
- Allow either ^D or ^Z entered to act as EOF.
These changes reflect the behavior of the VMS help system which the
hierarchical help system is modeled on.
This change signficantly improves header hygiene in the 3B2 project by
moving global symbols out of 3b2_defs.h and into the appropriate
individual module header files.
Each compilation unit now includes:
- its appropriate matching .h file
- any other .h files necessary for linting and compilation
Each header file in turn includes 3b2_defs.h, which contains truly
global symbols, and which pulls in sim_defs.h and exports global
devices.
The Rev 3 firmware does not check floppy controller status before
commanding a sector read, which can lead to calling sim_disk_rdsect()
on a detached unit. With this checkin, the simulator will no longer
attempt a read or write if the floppy unit is not attached.
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.
- Added a specific drive type RP05 which is the same size as the RP04
but can be distringuished by OS software.
- Restrict SET rpn BADBLOCK to only disk types which actually supported
the DEC Standard 144 bad block table.
- Fixed typo's in help and comments about DEC 044 vs DEC 144 and also
in pdp11_doc and vax780_doc documentation files.
As discussed in #1065
- Add column header to output of HELP device register list.
- Format HELP output for REGISTER, SET and SHOW commands to accommodate long
descriptor text (wrapping as needed).
- Add HELP DEVICE * to display help for all devices
This commit adds support for automatically running DGMON SBD diagnostic tests
on build.
Additionally, a small bug is fixed in simulator boot caused by failure to
parse boot switches.
