57bceb4da9 Fixed the LED (lamp) test, fixed Front Panel update on a machine RESET, and cleaned up the status update code a bit 2016-11-03 10:28:54 -07:00

aa2a25c5ec Minor Debugger improvements, notes, etc, while debugging the PDP-11 BASIC 2016-10-20 22:56:29 -07:00

16b8b59f12 PDP-11/20 test machine can load BASIC from paper tape, but still has some trouble running it 2016-10-18 15:44:26 -07:00

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
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

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
05626a33cb Version number update 2016-10-10 18:19:17 -07:00

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
Jeff
e24d507aa2 Removed useless version numbers and dates from .js file headers 2016-10-06 16:22:24 -07:00

795d57839b Cleaned up the decoding SRCMODE and DSTMODE operands, should be less confusing now 2016-10-04 17:22:25 -07:00
