- Previously the Option ROM device (OR) logic improperly used the UNIT
UNIT_ATT flag to indicate a devices with Option ROM support. This
bit has specific meaning to many SCP capabilities while there are
numerous device specific fields in the UNIT structure which DEVICEs
can use as needed.
- Enhance SCP SHOW output for Option ROM units to indicate the DEVICE
which each enabled ROM is related to.
Fixes#1210
Simulators built with DONT_USE_INTERNAL_ROM defined will not have hte
binary of the needed ROM or boot components build into the simulator
binaries. However, they will automatically and transparently fetch the
neeeded ROM or boot code from the web when these binary files aren't
available locally.
- Different VAX models had different groups of instructions which were
implemented in hardware vs trappng to the OS for emulation. Functionality
has been added to differentiate the various mix of instruction groups for
different models and to display both the groups and the actual instructions.
- Visibility to Instruction groups is provided by SHOW CPU INSTRUCTIONS
and the list of the active instructions implemented and emulated via
SHOW CPU -V INSTRUCTIONS.
- The MicroVAX I CPU handled some execution fault conditions differently
from other VAX systems these differences are now specifically handled.
- Add build time test support to MicroVAX I running EHKAA v1.13
suggested in #683
- Add more CPU debug details relating to exception and interrupt processing
