B5500: Initial checking of simulator for current simh The B5500 simulator supports the following peripherals. Two CPUs with between 4K and 32K of memory. The second CPU can be enabled with "set cpu1 enable". "set cpu1 disable" disables the second CPU. Up to 4 floating IO channels. Individual channels can be enabled with "set io# enable", or "set io# disable". There are two card readers. The second reader is disabled by default. There is one Card Punch. The Card reader and Card Punch support the following options: set cr format= auto - will automatically determine the format based on the text it recieves. text Text based cards. Tabs are converted to the correct number of spaces. A record of ~raw octal will enter a binary card. ~eor will enter a 7/8/9 punch in column 1. ~eof will enter a 6/7/9 punch in column 1. ~eoi will enter a 6/7/8/9 punch in column 1. ~~ will enter a ~ as the first character. bin Binary Card format: Each record 160 characters. First characters 6789---- Second character 21012345 111 Top 4 bits of second character are 0. It is unlikely that any other format could look like this. bcd BCD Format: Each record variable length (80 chars or less). Record mark has bit 7 set. Bit 6 is even parity. Bits 5-0 are character. cbn CBN Format: Each record 160 charaters. First char has bit 7 set. Rest set to 0. Bit 6 is odd parity. Bit 5-0 of first character are top 6 bits of card. Bit 5-0 of second character are lower 6 bits of card. For punch format of auto if the card can't be converted to text it is output as a raw record. There are two line printers, the second one is disabled by default. The LP supports the option "set lp# linesperpage=#" which determines when the printer will force out a page break. There are up to 16 mag tape drives, the format is controlled by the standard simh format control for tapes. These are 6 bit tapes, 1 character per record with parity. Units 8-16 are disabled by default. There are up to two drum units DR0 and DR1. These can either be attached to a file or set to AUXMEM. Setting to AUXMEM causes them to exist only during the given simh run. Setting back to DRUM will clear whatever was stored on the drum. To enable use of DRUM on XV the following options should be turned on "DRA,DRB,CODEOLAY,DATAOLAY". MCP will then use the drum as a overlay device instead of the disk system. Disks can be attached to the various ESU's, ESU0-9 are on DKA by default, ESU10-19 are on DKB. If "set dk1 dfx" is set, then ESU10-19 are not used and the disks are shared by both DKA and DKB. To use more then 10 ESU's in a non shared mode, a new version of MCP must be created. MCP must be compiled with DFX option set to false. For MCP XV DKBNODFX must also be set to true. ESU units can be set to MODI or MODIB. MODIB will double the size of the drive. The DTC can be attached to a telnet port with "attach dtc #" to enable dialup access to the sim. The loader card for the card reader is: ~raw0104441100204231524012004000004444550211002041317700000000000024045303040243 00050000006501004131011041310055005500000062005042310000006600304231000000720010 42310000007675610165001002310010413100040107202500440106202533554061256520252265 20251765202514655355536117650000004401062025155522610165225572610465044101160500 4131 This card should be all in one line.

The sim_frontpanel API provides a programatic interface to start and control any simulator without any special additions to the simulator code.
A new capability has been added which allows a TELNET Connection to a user designated port so that some out of band commands can be entered to manipulate and/or adjust a running simulator. The commands which enable and control this capability are SET REMOTE TELNET=port, SET REMOTE CONNECTIONS=n, SET REMOTE TIMEOUT=seconds, and SHOW REMOTE.
The remote console facility has two modes of operation: 1) single command mode. and 2) multiple command mode.
In single command mode you enter one command at a time and aren‘t concerned about what the simulated system is doing while you enter that command. The command is executed once you’ve hit return. In multiple command mode you initiate your activities by entering the WRU character (usually ^E). This will suspend the current simulator execution. You then enter commands as needed and when you are done you enter a CONTINUE command. While entering Multiple Command commands, if you fail to enter a complete command before the timeout (specified by “SET REMOTE TIMEOUT=seconds”), a CONTINUE command is automatically processed and simulation proceeds.
A subset of normal simh commands are available for use in remote console sessions. The Single Command Mode commands are: ATTACH, DETACH, PWD, SHOW, DIR, LS, ECHO, HELP The Multiple Command Mode commands are: EXAMINE, IEXAMINE, DEPOSIT, EVALUATE, ATTACH, DETACH, ASSIGN, DEASSIGN, STEP, CONTINUE, PWD, SAVE, SET, SHOW, DIR, LS, ECHO, HELP
A remote console session will close when an EOF character is entered (i.e. ^D or ^Z).
RQ has new disk types: RC25, RCF25, RA80 RQ device has a settable controller type (RQDX3, UDA50, KLESI, RUX50) RQ disks default to Autosize without regard to disk type RQ disks on PDP11 can have RAUSER size beyond 2GB DMC11/DMR11 DDCMP DECnet device simulation. Up to 8 DMC devices are supported. Packet transport is via TCP or UDP connections. KDP11 on PDP11 for DECnet DUP11 on PDP11 for DECnet connectivity to talk to DMC, KDP or other DUP devices DZ on Unibus systems can have up to 256 ports (default of 32), on Qbus systems 128 port limit (default of 16). DZ devices optionally support full modem control (and port speed settings when connected to serial ports). TU58 device support for all PDP11 and VAX systems. DHU11 (device VH) on Unibus systems now has 16 ports per multiplexer. XQ devices (DEQNA, DELQA and DELQA-T) are bootable on Qbus PDP11 simulators XQ and XU devices (DEQNA, DELQA, DELQA-T, DEUNA and DELQA) devices can now directly communicate to a remote device via UDP (i.e. a built-in HECnet bridge). XQ and XU devices (DEQNA, DELQA, DELQA-T, DEUNA and DELQA) devices can now optionally throttle outgoing packets which is useful when communicating with legacy systems on a local LAN which can easily get over run when packets arrive too fast. MicroVAX 3900 has QVSS (VCB01) board available. MicroVAX 3900 and MicroVAX II have SET CPU AUTOBOOT option MicroVAX 3900 has a SET CPU MODEL=(MicroVAX|VAXServer|VAXStation) command to change between system types MicroVAX I has a SET CPU MODEL=(MicroVAX|VAXSTATION) command to change between system types MicroVAX II has a SET CPU MODEL=(MicroVAX|VAXSTATION) command to change between system types
KDP11 (from Timothe Litt) for DECnet connectivity to simulators with DMC, DUP or KDP devices DMR11 for DECnet connectivity to simulators with DMC, DUP or KDP devices on TOPS10.
Support for SDS internal ASCII character encoding during display and data entry. Allow breakpoints to be qualified by normal, monitor or user mode. Fix CPU, RAD, MUX and I/O bugs that prevented SDS Time Share System Monitor and Executive from executing properly.
Added support for TCP connections using IPv4 and/or IPv6. Logging - Traffic going out individual lines can be optionally logged to files Buffering - Traffic going to a multiplexor (or Console) line can optionally be buffered while a telnet session is not connected and the buffered contents will be sent out a newly connecting telnet session. This allows a user to review what may have happened before they connect to that session. Serial Port support based on work by J David Bryan and Holger Veit Serial Console Support Separate TCP listening ports per line Outgoing connections per line (virtual Null Modem cable). Packet sending and reception semantics for simulated network device support using either TCP or UDP transport. Input character rates reflect the natural character arrival time based on the line speed.
Added support for monochrome displays with optional keyboards and mice.
The VAXstation QVSS device (VCB01) simulation uses this capability. Host platforms which have libSDL available can leverage this functionality.
* Disk and Tape I/O can be asynchronous. Asynchronous support exists for pdp11_rq, pdp11_rp and pdp11_tq devices (used by VAX and PDP11 simulators). * Multiplexer I/O (Telnet and/or Serial) can be asynchronous. Asynchronous support exists for console I/O and most multiplexer devices. (Still experimental - not currently by default)
* UDP packet transport. Direct simulator connections to HECnet can be made without running a local packet bridge program. * NAT packet transport. Simulators which only speak TCP/IP (No DECnet) and want to communicate with their host systems and/or directly to the Internet can use NAT packet transport. This also works for WiFi connected host systems. * Packet Transmission Throttling. When connected to a LAN which has legacy network adapaters (DEQNA, DEUNA) on legacy systems, it is very easy for a simulated system to overrun the receiving capacity of the older systems. Throttling of simulated traffic delivered to the LAN can be used to mitigate this problem. * Reliable MAC address conflict detection.
RAW Disk Access (including CDROM) Virtual Disk Container files, including differencing disks
Simulators which have boot commands which load constant files as part of booting have those files imbedded into the simulator executable. The imbedded files are used if the normal boot file isn't found when the simulator boots. Specific examples are: VAX (MicroVAX 3900 - ka655x.bin), VAX8600 (VAX 8600 - vmb.exe), VAX780 (VAX 11/780 - vmb.exe), VAX750 (VAX 11/750 - vmb.exe, ka750_old.bin, ka750_new.bin), VAX730 (VAX 11/730 - vmb.exe), VAX610 (MicroVAX I - ka610.bin), VAX620 (rtVAX 1000 - ka620.bin), VAX630 (MicroVAX II - ka630.bin)
The following extensions to the SCP command language without affecting prior behavior:
GOTO <Label> Command is now available. Labels are lines in which the first non whitespace character is a ":". The target of a goto is the first matching label in the current do command file which is encountered. Since labels don't do anything else besides being the targets of goto's, they could be used to provide comments in do command files, for example (":: This is a comment") SET ON Enables error trapping for currently defined traps (by ON commands) SET NOON Disables error trapping for currently defined traps (by ON commands) RETURN Return from the current do command file execution with the status from the last executed command RETURN <statusvalue> Return from the current do command file execution with the indicated status. Status can be a number or a SCPE_<conditionname> name string. ON <statusvalue> commandtoprocess{; additionalcommandtoprocess} Sets the action(s) to take when the specific error status is returned by a command in the currently running do command file. Multiple actions can be specified with each delimited by a semicolon character (just like breakpoint action commands). ON ERROR commandtoprocess{; additionalcommandtoprocess} Sets the default action(s) to take when any otherwise unspecified error status is returned by a command in the currently running do command file. Multiple actions can be specified with each delimited by a semicolon character (just like breakpoint action commands). ON <statusvalue> ON ERROR Clears the default actions to take when any otherwise unspecified error status is returned by a command in the currently running do command file.
Error traps can be taken for any command which returns a status other than SCPE_STEP, SCPE_OK, and SCPE_EXIT.
ON Traps can specify any status value from the following list: NXM, UNATT, IOERR, CSUM, FMT, NOATT, OPENERR, MEM, ARG, STEP, UNK, RO, INCOMP, STOP, TTIERR, TTOERR, EOF, REL, NOPARAM, ALATT, TIMER, SIGERR, TTYERR, SUB, NOFNC, UDIS, NORO, INVSW, MISVAL, 2FARG, 2MARG, NXDEV, NXUN, NXREG, NXPAR, NEST, IERR, MTRLNT, LOST, TTMO, STALL, AFAIL. These values can be indicated by name or by their internal numeric value (not recommended).
Interactions with ASSERT command and “DO -e”: DO -e is equivalent to SET ON, which by itself it equivalent to “SET ON; ON ERROR RETURN”. ASSERT failure have several different actions: * If error trapping is not enabled then AFAIL causes exit from the current do command file. * If error trapping is enabled and an explicit “ON AFAIL” action is defined, then the specified action is performed. * If error trapping is enabled and no “ON AFAIL” action is defined, then an AFAIL causes exit from the current do command file.
Other related changes/extensions: The “!” command (execute a command on the local OS), now returns the command's exit status as the status from the “!” command. This allows ON conditions to handle error status responses from OS commands and act as desired.
The EXPECT command now exists to provide a means of reacting to simulator output and the SEND command exists to inject data into programs running within a simulator.
EXPECT {HALTAFTER=n,}"\r\nPassword: " SEND {AFTER=n,}{DELAY=m,}"mypassword\r" or EXPECT {HALTAFTER=n,}"\r\nPassword: " SEND {AFTER=n,}{DELAY=m,}"mypassword\r"; GO

Token “%0” expands to the command file name. Token %n (n being a single digit) expands to the n'th argument Tonen %* expands to the whole set of arguments (%1 ... %9)
The input sequence “%” represents a literal “%”, and “\” represents a literal "". All other character combinations are rendered literally.
Omitted parameters result in null-string substitutions.
A Tokens preceeded and followed by % characters are expanded as environment variables, and if one isn't found then can be one of several special variables:
%DATE% yyyy-mm-dd %TIME% hh:mm:ss %DATETIME% yyyy-mm-ddThh:mm:ss %LDATE% mm/dd/yy (Locale Formatted) %LTIME% hh:mm:ss am/pm (Locale Formatted) %CTIME% Www Mmm dd hh:mm:ss yyyy (Locale Formatted) %DATE_YYYY% yyyy (0000-9999) %DATE_YY% yy (00-99) %DATE_MM% mm (01-12) %DATE_DD% dd (01-31) %DATE_WW% ww (01-53) ISO 8601 week number %DATE_WYYYY% yyyy (0000-9999) ISO 8601 week year number %DATE_D% d (1-7) ISO 8601 day of week %DATE_JJJ% jjj (001-366) day of year %TIME_HH% hh (00-23) %TIME_MM% mm (00-59) %TIME_SS% ss (00-59) %STATUS% Status value from the last command executed %TSTATUS% The text form of the last status value %SIM_VERIFY% The Verify/Verbose mode of the current Do command file %SIM_VERBOSE% The Verify/Verbose mode of the current Do command file %SIM_QUIET% The Quiet mode of the current Do command file %SIM_MESSAGE% The message display status of the current Do command file
Environment variable lookups are done first with the precise name between the % characters and if that fails, then the name between the % characters is upcased and a lookup of that valus is attempted.
The first Space delimited token on the line is extracted in uppercase and then looked up as an environment variable. If found it the value is supstituted for the original string before expanding everything else. If it is not found, then the original beginning token on the line is left untouched.
commands can be aliases with environment variables. For example:
sim> set env say=echo sim> say Hello there Hello there
The SHIFT command will shift the %1 thru %9 arguments to the left one position.
Simulators for the Windows platform are built and made available on a regular basis (at least once a week if changes have been made to the codebase).
The prebuilt Windows binaries will run on all versions of Microsoft Windows from Windows XP onward.
They can be accessed at https://github.com/simh/Win32-Development-Binaries
Several relatively recent versions should be available which you can download and use directly.
First download the latest source code from the github repository's master branch at https://github.com/simh/simh/archive/master.zip
Depending on your host platform one of the following steps should be followed:
If you are interested in using a simulator with Ethernet networking support (i.e. one of the VAX simulators or the PDP11), then you should make sure you have the correct networking components available. The instructions in https://github.com/simh/simh/blob/master/0readme_ethernet.txt describe the required steps to get ethernet networking components installed and how to configure your environment.
See the 0readme_ethernet.txt file for details about the required network components for your platform. Once your operating system build environment has the correct networking components available the following command will build working simulators:
$ make {simulator-name (i.e. vax)}
Compiling on windows is supported with recent versions of Microsoft Visual Studio (Standard or Express) and using GCC via the MinGW environment. Things may also work under Cygwin, but that is not the preferred windows environment. Not all features will be available as well as with either Visual Studio or MinGW.
The file https://github.com/simh/simh/blob/master/Visual%20Studio%20Projects/0ReadMe_Projects.txt describes the required steps to use the setup your environment to build using Visual Studio.
The file https://github.com/simh/simh/blob/master/Visual%20Studio%20Projects/0ReadMe_Projects.txt describes the required steps to use the setup your environment to build using MinGW.
Download the latest source code as a zip file from: https://github.com/simh/simh/archive/master.zip
Unzip it in the directory that you want SIMH to reside in. Unpack it and set the file attributes as follows:
$ unzip simh-master.zip $ set default [.simh-master] $ set file/attri=RFM:STM makefile,*.mms,[...]*.c,[...]*.h,[...]*.txt
Simulators with ethernet network devices (All the VAX simulators and the PDP11) can have functioning networking when running on Alpha or IA64 OpenVMS.
In order to build and run simulators with networking support, the VMS-PCAP package must be available while building your simulator. The simh-vms-pcap.zip file can be downloaded from https://github.com/simh/simh/archive/vms-pcap.zip
This link will return a file called simh-vms-pcap.zip which should be unpacked as follows:
$ unzip -aa simh-vms-pcap.zip $ rename [.simh-vms-pcap]pcap-vms.dir []
The PCAP-VMS components are presumed (by the descript.mms file) to be located in a directory at the same level as the directory containing the simh source files. For example, if these exist here:
[]descrip.mms []scp.c etc.
Then the following should exist: [-.PCAP-VMS]BUILD_ALL.COM [-.PCAP-VMS.PCAP-VCI] [-.PCAP-VMS.PCAPVCM] etc.
To build simulators:
On a VAX use:
$ MMx
On a Alpha & IA64 hosts use:
$ MMx ! With Ethernet support $ MMx/MACRO=(NONETWORK=1) ! Without Ethernet support
