Only SCP libraries should be including additional OS specific include
files since they cover both:
1) Are responsible for platform specific details integrated into simh
support
and
2) Implement extended functionality optimally considering the proper
behaviors to cooperate with the simh event system and existing
capabilities.
Simulator code can optionally include any of these system include files:
<stddef.h>, <stdlib.h>, <stdio.h>, <stdarg.h>, <string.h>, <errno.h>.
<limits.h>, <ctype.h>, <math.h>, <setjmp.h>
Such inclusion will be redundant with what is already provided here
by sim_defs.h. Simulator code should include SCP provided include files:
"scp.h", "sim_card.h", "sim_console.h", "sim_disk.h", "sim_ether.h",
"sim_fio.h", "sim_imd.h", "sim_scsi.h", "sim_serial.h", "sim_tape.h",
"sim_timer.h", "sim_tmxr.h", "sim_video.h"
depending on the specific needs of the device being simulated.
Under certain circumstances, the timer resolution in the Version 3
could become coarse enough that very short timer intervals would lead
to an infinite loop of bus errors when running timer firmware
diagnostics.
This change adds support for printing to an attached text file via the
Centronics port of a simulated PORTS feature card. A new device named
"LPT" has been added. See "help lpt" for documentation.
Additionally, there has been a fix to a bug in the SCSI tape boot
implementation and a very minor bug fix to the Rev 3 MMU.
After adding the sim_clock_precalibrate_commands, the PC was not zero
at the sim> prompt after loading altairz80.
Set CPU_S to zero in cpu_reset to address this issue.
This corrects an error that caused SIO reject when SIO occured before
a pending seek interrupt on a different device.
- Move the interrupt pending test from sigma_io.c into each device.
- Make the sigma_dp.c test a special case that looks for pending
seek interrupts.
While working on the AltairZ80 documentation, I found some problems
with the SOL20 registers and fixed some formatting issues.
Added static and "vdm1_" prefix to "charset" variable in s100_vdm1.c
This PR adds support for the Processor Technology VDM-1 display adapter and Sol-20 computer system. The VDM-1 was integrated into the Sol-20 but has been separated out into its own device.
This PR adds the following devices to the AltairZ80 simulator:
VDM1 - Processor Technology VDM-1 display adapter
SOL20 - Processor Technology SOL20 with SOLOS ROMs
SOL20K - SOL20 Keyboard (callback from VDM1)
SOL20T - SOL20 Tape (reads/writes cassette file images)
SOL20S - SOL20 Serial Port (TMXR capable)
SOL20P - SOL20 Printer Port (TMXR capable)
Used to initialize SCP timers to prevent problems during simulator startup
when THROTTLE is being used.

- Builds x86 and x64 regular snapshots.
x64: Mon Wed Fri
x86: Tue Thu Sat
ARM: Mon Thu Sun (ARM not enabled)
- Builds x64 on closed pull request, Release
- Manual trigger allows selection of ref, platform,
architecture, config, disposition
- Releases and daily snapshots are deployed automagically
- VS Project 2022 files updated for ARM, but not setup for
cross-builds (BuildROMs) or tested on ARM (no hardware)
- Fix makefile tests for cygwin
Proper initialization of the ADCS6 unit data structure depended on the
ADCS6 device being enabled. In cases where the ADCS6 unit was not
enabled, non-debug builds may crash on some host platforms depending on
compiler/memory layout.
This is to prevent confusion when questions come in.
Plus, a little advertising never hurts.
The version output will now include "Open SIMH", and the version
number will be '4.1.*' rather than '4.0.*'.
