This commit adds a "PMMI" device to the AltairZ80 VM that emulates
the PMMI Communications MM-103 MODEM & Communications Adapter.
This device was added at the request of a Facebook user that is
attempting to preserve and document various relevant communications
programs for CP/M and allow users to experience communicating and
sharing information with other remote computers of the same time
period, all on modern hardware.
This device attempts to emulate the MC6860L digital modem chip in
such a way that communications software written for the PMMI MM-103 can
communicate over a serial port or socket without a phone line or
the ability to MOdulate/DEModulate data over a phone line.
This commit adds two new devices, "M2SIO0" and "M2SIO1", to the AltairZ80
VM. These two independent devices emulate "raw" 88-2SIO ports that can
be used instead of the "SIO" device for attaching socket and serial
ports using TMXR.
- Avoid building a published version with uncommitted files in the
working directory
- Confirm existence of remote named origin and fetch master branch
- Add automatic force to push remote Win32-Development-Binaries
repo when resetting the binary directory
Refactor in preparation for the addition of a Rev 3 simulator for the
3B2/1000 system.
This change also includes a full cleanup of the rat's-nest of includes
and externs that plagued the 3B2 simulator and made it difficult to
understand and maintain. Headers are now required in the following
order:
compilation unit -> "3b2_defs.h" -> {... dependencies ...}
Finally, HELP has been added to the CPU device.
Similar to the build_ming.bat procedure which will invoke MinGW to
biuild siimulators, this procedure will rebuild all of SIMH simulators using
Visual Studio.
If this procedure is not invoked from a Developer Command Prompt
then the VS2008 tools are preferred if VS2008 is installed,
otherwise the installed Visual Studio tools will be used
prefering newer Visual Studio versions over older ones.
If this procedure is invoked from a Developer Command Prompt
then the tool chain provided with the command prompt is used
to build the simh projects.
A single argument to this procedure may be the word Debug, which
will cause Debug binaries to be build rather than the Release
binaries which is the default.
This file is the README which will land in a newly reset
Win32-Development-Binaries repository. It has been revised to
suggest that forking the Win32-Development-Binaries repo need
never be done and is only wasteful of space on GitHub.
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.
Added support for Lines per page to LP10.
Fixed issues with 7 track tapes on TM10.
Updated user guides
This change adds support for the WE32106 Math Acceleration Unit (MAU).
The WE32106 is an IEEE-754 1985 compatible floating point math
acceleration unit that was an optional component on the 3B2/310 and
3B2/400.
The MAU is implemented using software floating point routines. As
always, there may be bugs, but the MAU currently passes extensive
floating point tests with exactly the same results as a real 3B2/400
equipped with a physical MAU, so I hope these are few.
