Because some key files have changed, V3.0 should be unzipped to a clean directory. 1. New Features in 3.0-0 1.1 SCP and Libraries - Added ASSIGN/DEASSIGN (logical name) commands. - Changed RESTORE to unconditionally detach files. - Added E11 and TPC format support to magtape library. - Fixed bug in SHOW CONNECTIONS. - Added USE_ADDR64 support 1.2 All magtapes - Magtapes support SIMH format, E11 format, and TPC format (read only). - SET <tape_unit> FORMAT=format sets the specified tape unit's format. - SHOW <tape_unit> FORMAT displays the specified tape unit's format. - Tape format can also be set as part of the ATTACH command, using the -F switch. 1.3 VAX - VAX can be compiled without USE_INT64. - If compiled with USE_INT64 and USE_ADDR64, RQ and TQ controllers support files > 2GB. - VAX ROM has speed control (SET ROM DELAY/NODELAY). 2. Bugs Fixed in 3.01-0 2.1 VAX - Fixed CVTfi bug: integer overflow not set if exponent out of range - Fixed EMODx bugs: o First and second operands reversed o Separated fraction received wrong exponent o Overflow calculation on separated integer incorrect o Fraction not set to zero if exponent out of range - Fixed interval timer and ROM access to pass power-up self-test even on very fast host processors (fixes from Mark Pizzolato). 2.2 1401 - Fixed mnemonic, instruction lengths, and reverse scan length check bug for MCS. - Fixed MCE bug, BS off by 1 if zero suppress. - Fixed chaining bug, D lost if return to SCP. - Fixed H branch, branch occurs after continue. - Added check for invalid 8 character MCW, LCA. - Fixed magtape load-mode end of record response. 2.3 Nova - Fixed DSK variable size interaction with restore. 2.4 PDP-1 - Fixed DT variable size interaction with restore. 2.5 PDP-11 - Fixed DT variable size interaction with restore. - Fixed bug in MMR1 update (found by Tim Stark). - Added XQ features and fixed bugs: o Corrected XQ interrupts on IE state transition (code by Tom Evans). o Added XQ interrupt clear on soft reset. o Removed XQ interrupt when setting XL or RL (multiple people). o Added SET/SHOW XQ STATS. o Added SHOW XQ FILTERS. o Added ability to split received packet into multiple buffers. o Added explicit runt and giant packet processing. 2.6 PDP-18B - Fixed DT, RF variable size interaction with restore. - Fixed MT bug in MTTR. 2.7 PDP-8 - Fixed DT, DF, RF, RX variable size interaction with restore. - Fixed MT bug in SKTR. 2.8 HP2100 - Fixed bug in DP (13210A controller only), DQ read status. - Fixed bug in DP, DQ seek complete. 2.9 GRI - Fixed bug in SC queue pointer management. 3. New Features in 3.0 vs prior releases N/A 4. Bugs Fixed in 3.0 vs prior releases N/A 5. General Notes WARNING: The RESTORE command has changed. RESTORE will now detach an attached file on a unit, if that unit did not have an attached file in the saved configuration. This is required to assure that the unit flags and the file state are consistent. WARNING: The compilation scheme for the PDP-10, PDP-11, and VAX has changed. Use one of the supplied build files, or read the documentation carefully, before compiling any of these simulators.

This file contains information about the XQ/SIM_ETHER package.
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
The XQ emulator is a host-independant software emulation of Digital's
|
|
DELQA (M7516) and DEQNA (M7504) Q-bus ethernet cards for the SIMH emulator.
|
|
|
|
The XQ emulator uses the Sim_Ether module to execute host-specific ethernet
|
|
packet reads and writes, since all operating systems talk to real ethernet
|
|
cards/controllers differently. The host-dependant Sim_Ether module currently
|
|
supports Windows, Linux, NetBSD, and OpenBSD.
|
|
|
|
Currently, the Sim_Ether module sets the selected ethernet card into
|
|
promiscuous mode to gather all packets, then filters out the packets that it
|
|
doesn't want. In Windows, packets having the same source MAC address as the
|
|
controller are ignored for WinPCAP compatibility (see Windows notes below).
|
|
|
|
If your ethernet card is plugged into a switch, the promiscuous mode setting
|
|
should not cause much of a problem, since the switch will still filter out
|
|
most of the undesirable traffic. You will only see "excessive" traffic if you
|
|
are on a direct or hub(repeater) segment.
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
Windows notes:
|
|
1. The Windows-specific code uses the WinPCAP 3.0 package from
|
|
http://winpcap.polito.it. This package for windows simulates the libpcap
|
|
package that is freely available for unix systems.
|
|
2. You must *install* the WinPCAP runtime package.
|
|
3. The first time the WinPCAP driver is used, it will be dynamically loaded,
|
|
and the user must be an Administrator on the machine to do so. If you need
|
|
to run as an unprivileged user, you must set the service to autostart. See
|
|
the WinPCAP documentation for details on the static load workaround.
|
|
4. WinPCAP loops packet writes back into the read queue. This causes problems
|
|
since the XQ controller is not expecting to read it's own packet. A fix
|
|
to the packet read filter was added to reject packets from the current MAC,
|
|
but this defeats DECNET's duplicate node number detection scheme. A more
|
|
correct fix for WinPCAP will be explored as time allows.
|
|
|
|
Building on Windows:
|
|
1. Install WinPCAP 3.0.
|
|
2. Put the required .h files (bittypes,devioctl,ip6_misc,packet32,pcap,
|
|
pcap-stdinc).h from the WinPCAP 3.0 developer's kit in the compiler's path
|
|
3. Put the required .lib files (packet,wpcap).lib from the WinPCAP 3.0
|
|
developer's kit in the linker's path
|
|
4. If you're using Borland C++, use COFF2OMF to convert the .lib files into
|
|
a format that can be used by the compiler.
|
|
5. Define USE_NETWORK if you want the network functionality.
|
|
6. Build it!
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
Linux, NetBSD, and OpenBSD notes:
|
|
1. You must run SIMH(scp) as root so that the ethernet card can be set into
|
|
promiscuous mode by the driver. Alternative methods for avoiding the
|
|
'run as root' requirement will be welcomed.
|
|
|
|
Building on Linux, NetBSD, and OpenBSD:
|
|
1. Get/install the libpcap package for your unix version. http://rpmfind.net
|
|
might be a useful site for finding the linux variants.
|
|
2. Use Make USE_NETWORK=1 if you want the network functionality.
|
|
3. Build it!
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
VAX simulator support:
|
|
|
|
An OpenVMS VAX v7.2 system with DECNET Phase IV, MultiNet 4.4a, and LAT 5.3 has
|
|
been successfully run. Other testers have reported success booting NetBSD also.
|
|
|
|
|
|
PDP11 simulator support:
|
|
|
|
An RT-11 v5.3 system with a freeware TCP/IP stack has been successfully run.
|
|
Other testers have reported that RSX with DECNET and the NetBSD operating
|
|
systems also work. RSTS/E v10.1 has preliminary support - RSTS/E boots and
|
|
enables the XH (XQ) device - DECNET and LAT software have not been tested.
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
Things planned for future releases:
|
|
1. PDP-11 bootstrap/bootrom
|
|
2. Full MOP implementation
|
|
3. DESQA support (if someone can get me the user manuals)
|
|
4. DETQA support [DELQA-Turbo] (I have the manual)
|
|
5. DEUNA/DELUA support
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
Things which I need help with:
|
|
1. Porting Sim_Ether packet driver to other host platforms, especially VMS.
|
|
2. Information about Remote MOP processing
|
|
3. VAX/PDP-11 hardware diagnotics image files and docs, to test XQ thoroughly.
|
|
4. Feedback on operation with other VAX/PDP-11 OS's.
