2ce661e141 Refer to all 11/45+ instructions as 11/45, rather than 11/70, since the 11/70 doesn't appear to have added any instructions to the 11/45's set 2016-10-15 13:34:02 -07:00

1e080e720e Debugger now actually prevents an undefined opcode from executing (until/unless you single-step it) 2016-10-15 11:59:48 -07:00

c14f919f4f Debugger now stops on undefined opcodes, as well as on unknown I/O accesses 2016-10-15 11:32:51 -07:00

3a7b769fa3 Added support to FileDump for generating binary dumps from MACRO11 listing (.lst) files, since I wasn't having much success with dumpobj or obj2hex.pl; note that this assumes a listing file produced by the macro11 cross-assembler written by Richard Krehbiel in 2001, updated in 2009, and maintained here: https://github.com/shattered/macro11. There are other versions of macro11 floating around, like the one in the simtools project that accompanies simh, and the one built for the Windows-based PDP11GUI app. 2016-10-15 11:05:38 -07:00

2a1be67727 In the spirit of the PCx86 Debugger, the PDP11 Debugger can now distinguish between virtual and physical addresses; physical addresses are specified with a leading '%'; this necessitated special CPU memory interfaces that mirror the Bus memory interfaces, which perform mapVirtualToPhysical() as needed, with traps disabled. 2016-10-13 13:11:11 -07:00

686396d726 Switched interrupt management to a new set of Trigger functions and static Trigger objects, eliminating the old InterruptQueue of constantly created/destroyed InterruptEvents 2016-10-13 10:20:11 -07:00

8bb978d7a9 Resolved a problem with the original timer implementation, where a call to setTimer() made in the middle of a CPU burst would not properly account for cycles already executed as part of the current burst 2016-10-12 22:08:45 -07:00

8315774b1d Implemented a fallback fix for UNIBUS addresses where a byte write is expected to modify the entire word 2016-10-11 16:08:32 -07:00

30e67a015b Fixed some idiosyncrasies involving the versioned folder names for the various emulators. Any compiled pdp*.js script (eg, pdp11.js) will be stored in the /versions/pdpjs folder, just as any compiled c1p*.js script will be stored in the /versions/c1pjs folder. Other emulators that don't use a "js" suffix in their name (eg, PCx86 and PC8080) are stored in /versions folders that mirror their names. 2016-10-11 12:19:54 -07:00

4c63c8a97f Quick change (perhaps temporary) to update LEDs on every WAIT transition (similar to the behavior of the original pdp11.js) 2016-10-11 10:47:09 -07:00

Jeff Parsons
6514836098 Cleaned up how memory and IOPAGE traps are triggered, how ODD byte-level IOPAGE accesses are handled, and how memory is dumped by the Debugger 2016-10-10 17:09:29 -07:00

1a1614a648 Simplify the Bus and Memory interfaces slightly, by enabling WORDBUS, which treats all word accesses as aligned; the CPU is has sole responsibility for detecting unaligned word addresses and trapping appropriatelu 2016-10-06 14:17:29 -07:00
