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.

22-Jul-03 RMS Updated for "hardware" RIM loader
|
||
Revised to detect I/O wait hang
|
||
05-Dec-02 RMS Added IOT skip support (required by drum)
|
||
14-Apr-99 RMS Changed t_addr to unsigned
|
||
|
||
The PDP-1 was Digital's first computer. The system design evolved during
|
||
its life, and as a result, specifications are sketchy or contradictory.
|
||
This simulator is based on the 1962 maintenance manual.
|
||
|
||
This simulator implements the following options:
|
||
|
||
Automatic multiply/divide Type 10
|
||
Memory extension control Type 15
|
||
Serial drum Type 24
|
||
Line printer control Type 62
|
||
Microtape (DECtape) control Type 550
