* AltairZ80: SS1: Fix disable after reset.
The CompuPro System Support 1 could not be disabled after enabled and
used due to timers causing it to be busy. Reset properly so that "set
ss1 disabled" works after reset.
* AltairZ80: wd179x: Properly reset 179x state.
* AltairZ80: M68K: Fix compile with VS2008.
* Musashi: Fix compilation with Visual Studio 2008.
* AltairZ80: M68K: Resolve warnings in softfloat.
* AltairZ80: Add headers to .vcproj
* VIDEO: Fix bug: vid_ready can be used uninitialized.
* VIDEO: Not all events come with a valid windowID.
* PDP11: Fix NG SET TYPE.
The sense of MATCH_CMD is reversed.
* display: Fix bug in NG display controller.
There should be a separate state for each of the eight displays.
* display: Symbolic constant for number of displays.
Take the version of the code from VAX/vax4nn_stddev.c and vax4xx_stddev.c,
and apply it to 730, 750, 780, 820 and 860.
If we can assume that clk_tps always remains 100, this can be simplified
further.
This avoids infecting SIMH with the GPL license, since readline,
very surprisingly, is GPL rather than LGPL.
The replacement package is "editline", which has a useable license.
This fixes issue #38 by setting the SDL_HINT_VIDEO_ALLOW_SCREENSAVER
hint to 1, leaving the screen saver enabled. SDL 2.0.2 had changed
the default to disable the screen saver.

This commit introduces dozens of changes to make the 3B2-700 simulator
fully functional and ready for wider use. In addition to 3B2-700
availability, this commit includes a tremendous amount of refactoring
of the 3B2-400 and common code to make the project structure easier to
maintain and reason about.
One final important change: ROM files are no longer included in the
source code. 3B2 ROM images must be obtained separately and loaded
into the simulator before boot.
Changes:
- The 3b2 target has been aliased to 3b2-400
- The formerly named 3b2-600 project has become 3b2-700
- SCSI QIC tape support has been added to sim_scsi.c
- Header files have been reworked to reduce complexity of includes
- Common code has been consolidated
- Timer code has been unified
This commit extends the existing DUP11/DPV11 support to add support for HDLC framing. There
is no requirement to support bit/byte stuffing, so the aim is simply to encapsulate/decapsulate
the datalink frame provided by the host driver.
DDCMP has been regression tested on VMS, RSX and TOPS20, and the HDLC mode was developed
and tested with VAX/VMS DECnet Phase V, only using the HDLC datalink implementation.
In theory this support is sufficient to allow Phase IV/V P.S.I and even VMS/SNA to be used,
but these remain to be demonstrated.
- Correct RBUF_GETLINE & RBUF_PUTLINE: these are both sensitive to
modeling DHU vs. DHV; the correct bit mask was not generated for DHU.
- Make certain the device presents 16 lines when modeling a DHU.
