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.
