This fixes the H flag handling for the 8080 CPU and corrects the parity
flag computation for the Z80 CPU for INI, OUTI, IND, OUTD, INIR, OTIR,
INDR and OTDR instructions. It is based on Thomas Eberhardt's work.
- Add common system includes used in may places which are allowed
and thus added directly in sim_defs.h.
- Separate completely private system data structures and system APIs
for use only by SCP library routines into sim_scp_private.h.
- Update README to describe differences with open-simh
- Allow SET NOAUTOSIZE and SET AUTOSIZE
- Document deprecation and possibly non functionality of MinGW
Windows build support
- bounds check accesses in get_rval and put_rval for circular registers
- extend unit tests for REGister sanity checks to include all macros
- add sanity checks for new REGister macros
Historically, if a configuration file explicitly set either a DEVICE's
ADDRESS or VECTOR, autoconfiguration was immediately disabled.
This change defers disabling autoconfigure until an explicitly setting
of a DEVICE address or VECTOR actually changes what had been previously
configured by autoconfigure.

Some simulators and/or devices may want to provide specific testing
activities outside of full simulator execution which often will require
external, potentially complicated setup.
Added KS10 support.
CPU Redid instruction decode to improve performance
Triple-I display cleanup.
Normalized end of line to DOS/Unix.
KL10 FE, Cleanup issues with TTY devices hanging simulator..
Fixed errors in RH20 device.
RP and TU drives more independent of RH controller.
The key change is the addition of:
When a simulator starts execution, the following sequence of simh command
files are executed if they are found:
1. If a file named simh.ini is located in your HOME directory, it is
executed.
2. If the simh.ini file in your HOME directory isn’t found, a file named
simh.ini in your current working directory is executed if it exists.
3. If the simulator is invoked with any arguments, then the arguments are
presumed to be a command file and possible arguments to that command
file which is executed.
4. If the simulator is invoked without any arguments, then a command file
with the same name as the simulator binary with .ini appended that is
located in the current working directory is executed.
Note, that up to 2 separate command files may be executed on simulator
startup. The simh.ini file allows the user to define local user
preferences that align with their personal goals for simulator execution
across all simulators that may be used on their system.
Steps 3 and 4 were inherited from simh v3.x. Steps 1 and 2 was inspired
by conversations with J. David Bryan in April of 2012. Some how it
never got documented.
- 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
The new REG_DEPOSIT register flag bit indicates that updates to a
REGister with this flag specified will invoke the sim_vm_reg_update
routine after the data has been updated.
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof
Update simh.doc to reflect this generic change.
