de916981f3 It is now possible to re-attach or re-load the current paper tape; re-attaching means repositioning it at the beginning, and re-loading means loading it into RAM again. Note that whenever you reload a tape, it's HIGHLY recommended that you reset the machine first, too. 2016-10-23 13:44:31 -07:00

9ecb9e948f More tweaks to the on-going tension between giving machine elements focus (especially problematic when there are multiple machines) and preventing the page from being yanked around 2016-10-23 09:24:26 -07:00

22e24697fe Fixed read/write breakpoints for instructions that snapshot the cycle count, and improved the disassembly of PC-relative operands 2016-10-21 13:45:01 -07:00
Jeff Parsons
3db1439b40 Improved Debugger focus handling, added a new zeroMemory() Bus interface, and updated the RAM component's reset() function to re-zero RAM and then restore any predefined contents 2016-10-21 12:15:02 -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

b1f8fca2d9 Re-enabled source maps, at least for the PDP-11 emulators (for now) 2016-10-14 09:30:17 -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

47767416a1 Added preliminary LED support 2016-10-11 10:20:39 -07:00

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

b3ba03d0a5 Got rid of runState, implemented a solution for WAIT 2016-09-29 11:04:33 -07:00
Jeff
c7dbfc02be Fixed CPU start/stop control; runCPU is now strictly a worker function, not a control interface (PDP-11 only; other CPUs still need to be updated to match) 2016-09-28 22:21:52 -07:00

b2294e2293 Use CPU timer functions (instead of browser timeout/interval functions) to control device interrupts/timeouts 2016-09-26 20:34:31 -07:00

3bd02c7e19 Bumped version to 1.30 in honor of the PDP11 module that's being integrated, along with my first attempt to use a newer version of the Closure Compiler (ie, the JavaScript version), as well as giving Gulp a try -- although Gulp leaves just as bad a taste in my mouth as Grunt did 2016-09-13 15:33:17 -07:00
