Notes For V3.0-1

Browse Source 
RESTRICTION: The FP15 and XVM features of the PDP-15 are only partially
debugged.  Do NOT enable these features for normal operations.

1. New Features in 3.0-1

1.1 PDP-1

- Added block loader format support to LOAD.
- Changed BOOT PTR to allow loading of all of the first bank of memory.

1.2 PDP-18b Family

- Added PDP-4 EAE support.
- Added PDP-15 FP15 support.
- Added PDP-15 XVM support.
- Added PDP-15 "re-entrancy ECO".
- Added PDP-7, PDP-9, PDP-15 hardware RIM loader support in BOOT PTR.

2. Bugs Fixed in 3.0-1

2.1 PDP-11/VAX

- Fixed bug in user disk size (found by Chaskiel M Grundman).

2.2 PDP-1

- Updated CPU, line printer, standard devices to detect indefinite I/O wait.
- Fixed incorrect logical, missing activate, break in drum simulator.
- Fixed bugs in instruction decoding, overprinting for line printer.

2.3 PDP-10

- Fixed bug in RP read header.

2.4 PDP-18b Family

- Fixed bug in PDP-4 line printer overprinting.
- Fixed bug in PDP-15 memory protect/skip interaction.
- Fixed bug in RF set size routine.
- Increased PTP TIME for PDP-15 operating systems.

2.5 PDP-8

- Fixed bug in DF, RF set size routine.

2.6 Nova

- Fixed bug in DSK set size routine.

2.7 1401

- Revised fetch to model hardware more closely.

2.8 Ibm1130

- Fixed bugs found by APL 1130.

2.9 Altairz80

- Fixed bug in real-time clock on Windows host.

2.10 HP2100

-- Fixed DR drum sizes.
-- Fixed DR variable capacity interaction with SAVE/RESTORE.

3. New Features in 3.0 vs prior releases

3.1 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

3.2 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.

3.3 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).

4. Bugs Fixed in 3.0 vs prior releases

4.1 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).

4.2 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.

4.3 Nova

- Fixed DSK variable size interaction with restore.

4.4 PDP-1

- Fixed DT variable size interaction with restore.

4.5 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.

4.6 PDP-18B

- Fixed DT, RF variable size interaction with restore.
- Fixed MT bug in MTTR.

4.7 PDP-8

- Fixed DT, DF, RF, RX variable size interaction with restore.
- Fixed MT bug in SKTR.

4.8 HP2100

- Fixed bug in DP (13210A controller only), DQ read status.
- Fixed bug in DP, DQ seek complete.

4.9 GRI

- Fixed bug in SC queue pointer management.
