Notes For V3.0-0
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.

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.
