Added BASE option to auxcpu to move memory region.
Fix errors in Card Reader/Card Punch translation and operation.
Fixed problems with ITS quantum timer.
Added support for System Concepts DC10 disk controller (Lars).
Fixed errors in Line Printer control codes.

Updated user guides
- Properly handle clock transitions when control flows back and forth
between instruction execution and simh commands.
- Changed Internal Timer from 10 Hz to the MAX(100Hz, HostOSClockHz)
- Changed default idle calibration percent to 50%
- Make sure that error cases (backwards and gap too big) properly advance
the real time while avoiding calibration.
- Fix selection of the calibrated clock.
- Fix logic that sets the idle percentage that controls calibration.
1) Support for new sim_card interface which supports stacking
of input decks.
2) Changes to allow IBM 704 to properly run Fortran II and allow
i7090 to be set to IBM 704 correctly.
3) Changes to allow 9IOTA diagnostics to pass.
1) Minor cleanup of some instruction execution to better match
flowcharts.
2) Changes to allow proper reboot if OS crashed.
3) Changes to terminal muliplexer to allow for simH expect/send
to work.
4) Some corrections to translation table.
5) Support for new sim_card interface. This includes support for
stacking of multiple decks on the input stream.
- Assure that Internal variables are referencable during expression evaluation
- Add DEVNAME.REGNAME format for referencing non unique registers in
expression evaluation.
- Extend global register search to also search known internal device list
registers
- Allow expression variable names to have _ as a character within in the name
New Hardware support:
- IBM 653 Storage Unit: provides machine opcodes
for Floating Point, Immediate Access Storage (IAS),
Three Index registers, Cards Punch-read
synchronizers 2 and 3.
New Software included:
- FORTRANSIT: version II (S), plus run time PACKAGE
with standard Fortran functions.
- Reorganized sw directory, separating each language
in its own folder. Each one Includes a 00_readme.txt
file with restoration notes and comments.
New features:
- Support for SOAP opcode mnemonics in addition
to regular IBM mnemonics
- FAST / REALTIME CPU options
- PROP pseudo register
- CARDDECK ECHOLAST command
Hardware support:
- Half cycle simulation
- Halt CPU simulation (^E on SimH console)
New Software included: Carnegie Internal Translator (IT)
New features
- Support for displaying SOAP symbolic instructions in debug information
- CardDeck internal command to split/join/print decks of cards
Bugs corrected:
- Fixed card format handling. Release 1 can only read TEXT format
- Removed superfluous line ends from debug strings.
- Better minus zero support
- Fixed unneeded prompt Really truncate memory [N] when setting memory size
These include simulators for the IBM 701, IBM 702, IBM 704, IBM 705,
IBM 705/3, IBM 709, IBM 1410/IBM 7010, IBM 7070, IBM 7080, IBM 7090
and IBM7094.
These basically were a collection of machines that shared a common
set it peripherals, Each group had its own instruction set, hence
different simulators.
IBM 701 -> i701
IBM 702/705/705/3/7080 -> i7080
IBM 7070/7074 -> i7070
IBM 1410/7010 -> i7010
IBM 704 -> i704
IBM 704/709/7090/7094 -> i7090
The i7090 can be set to simulate a IBM 704 however you end up
disabling almost everything, since the 704 did not have any channels.
A build option exists that allows this one to be built without all the
extra features.
The i7090 simulator’s implementation of the IBM 7094 is a more
complete implementation of the IBM 7094 which can run CTSS
while the existing simh I7094 can’t.
