Notes For V3.1-0
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 3.1-0 1.1 SCP and libraries - Added simulated Ethernet support for VMS, FreeBSD, Mac OS/X. - Added status return to tmxr_putc_ln. - Added sim_putchar_s to handle possible output stalls. 1.2 All DECtapes - Added "DECtape off reel" error stop. 1.3 All Asynchronous Consoles - Added support for output congestion stall if using a Telnet connection. 1.4 PDP-1 - Added Type 23 parallel drum support. 1.5 PDP-8 - Added instruction history. - Added TSC8-75 option support for ETOS. - Added TD8E DECtape support. 1.6 PDP-18b - Added instruction history. - Changed PDP-9, PDP-15 API default to enabled. 1.7 PDP-11 - Added support for 18b only Qbus devices. - Formalized bus and addressing definitions. - Added control to enable/disable autoconfiguration. - Added stub support for second Unibus Ethernet controller. 1.7 Interdata 32b - Added instruction history. 1.8 Eclipse - Added floating point support. - Added programmable interval timer support. 1.9 H316 - Added DMA/DMC support. - Added fixed head disk support. - Added moving head disk support. - Added magtape support. 1.10 IBM 1130 (Brian Knittel) - Added support for physical card reader, using the Cardread interface (www.ibm1130.org/sim/downloads). - Added support for physical printer (flushes output buffer after each line). 2. Bugs Fixed in 3.1-0 2.1 SCP and libraries - Fixed numerous bugs in Ethernet library. 2.2 All DECtapes - Fixed reverse checksum value in 'read all' mode. - Simplified (and sped up) timing. 2.3 PDP-8 - Fixed bug in RX28 read status (found by Charles Dickman). - Fixed RX28 double density write. 2.4 PDP-18b - Fixed autoincrement bug in PDP-4, PDP-7, PDP-9. 2.5 PDP-11/VAX - Revised RQ MB->LBN conversion for greater accuracy. - Fixed bug in IO configuration (found by David Hittner). - Fixed bug with multiple RQ RAUSER drives. - Fixed bug in second Qbus Ethernet controller interrupts. 2.6 Nova/Eclipse - Fixed bugs in DKP flag clear, map setup, map usage (Charles Owen). - Fixed bug in MT, reset completes despite I/O reset (Charles Owen). - Fixed bug in MT, space operations return word count (Charles Owen). 2.7 IBM 1130 (Brian Knittel) - Fixed bug in setting carry bit in subtract and subtract double. - Fixed timing problem in console printer simulation. 2.8 1620 - Fixed bug in branch digit (found by Dave Babcock). 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). 3.4 PDP-1 - Added block loader format support to LOAD. - Changed BOOT PTR to allow loading of all of the first bank of memory. - The LOAD command takes an optional argument specifying the memory field to be loaded. - The PTR BOOT command takes its starting memory field from the TA (address switch) register. 3.5 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. 4. Bugs Fixed in 3.0 vs prior releases 4.1 SCP and Libraries - Fixed end of file problem in dep, idep. - Fixed handling of trailing spaces in dep, idep. 4.2 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). - Fixed bug in user disk size (found by Chaskiel M Grundman). 4.3 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. - Revised fetch to model hardware more closely. - Fixed tape read end-of-record handling based on real 1401. - Added diagnostic read (space forward). 4.4 Nova - Fixed DSK variable size interaction with restore. - Fixed bug in DSK set size routine. 4.5 PDP-1 - Fixed DT variable size interaction with restore. - 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. - Fixed system hang if continue after PTR error. - Fixed PTR to start/stop on successive rpa instructions. 4.6 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. - Fixed bug in user disk size (found by Chaskiel M Grundman). 4.7 PDP-18B - Fixed DT, RF variable size interaction with restore. - Fixed MT bug in MTTR. - 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. - Fixed priorities in PDP-15 API (differs from PDP-9). - Fixed sign handling in PDP-15 EAE unsigned mul/div (differs from PDP-9). - Fixed bug in CAF, clears API subsystem. 4.8 PDP-8 - Fixed DT, DF, RF, RX variable size interaction with restore. - Fixed MT bug in SKTR. - Fixed bug in DF, RF set size routine. 4.9 HP2100 - Fixed bug in DP (13210A controller only), DQ read status. - Fixed bug in DP, DQ seek complete. - Fixed DR drum sizes. - Fixed DR variable capacity interaction with SAVE/RESTORE. 4.10 GRI - Fixed bug in SC queue pointer management. 4.11 PDP-10 - Fixed bug in RP read header. 4.12 Ibm1130 - Fixed bugs found by APL 1130. 4.13 Altairz80 - Fixed bug in real-time clock on Windows host. 4.14 1620 - Fixed bug in immediate index add (found by Michael Short).
