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.
The CFGTST register MTYPE subfield should describe the additional memory
beyond 2MB on the processor board. Previous logic attempted to describe
the total system memory and the net result didn't fit into the 3 bit field and
thus said no additional memory is present.
The consequence of this new amount of memory is that ALL of it is tested
during the power on self test and thus it takes significantly longer to get to
the >>> prompt.
As reported in #944
- 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
