0f4cbd6e7b Added my first PDP-11 add-on device component (PC11) 2016-10-15 16:32:59 -07:00

b79146880d Debugger now restricts opcodes to the current CPU model 2016-10-15 15:01:39 -07:00
Jeff Parsons
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
Jeff Parsons
1e080e720e Debugger now actually prevents an undefined opcode from executing (until/unless you single-step it) 2016-10-15 11:59:48 -07:00
Jeff Parsons
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

854b40c419 Cleaned up PDP-11/70 configs 2016-10-13 16:35:10 -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
Jeff Parsons
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
Jeff Parsons
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
Jeff Parsons
58d358b51e Switching to new interrupt triggers 2016-10-12 16:40:47 -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
Jeff Parsons
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
47767416a1 Added preliminary LED support 2016-10-11 10:20:39 -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
Jeff Parsons
ae4fbeb489 Improved IOPAGE management 2016-10-08 11:09:14 -07:00

Jeff Parsons
c69ebb7bcb Factored out mapVirtualToPhysical() calls when MMU not enabled, and fixed HALT (it actually halts the CPU now) 2016-10-07 09:49:02 -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
Jeff
4e8d4e95d8 Picked up fixes from the gh-pages rollout 2016-10-06 10:09:41 -07:00

21b4fe4942 Renamed PDP11js to PDPjs (mostly a cosmetic change, except for the versions directory, and less of a mouthful) 2016-10-05 17:43:46 -07:00
