9ab8d5eb5f Trying to keep the focus code synced 2016-10-23 09:30:01 -07:00
Jeff Parsons
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

49b5e34ba2 Remove all debugger.js files when running uncompiled without the Debugger, and some PDP-11 layout fixes 2016-10-22 01:36:45 -07:00
Jeff Parsons
f5b879db60 README updates 2016-10-22 00:03:28 -07:00
Jeff Parsons
35f931f492 Fixed stepCPU() so that, if a Debugger is present, it always calls checkInstruction() on at least the first instruction of a run, so that Debugger features like skipping over an initial HALT opcode works properly 2016-10-21 23:24:27 -07:00
Jeff Parsons
5808778351 Added getTrapStatus() so that the Debugger can display trap information whenever a trap has just occurred, updated FileDump to store 'load' and 'exec' properties in MACRO-11 listing dumps (so that the individual machine files don't have to specify hard-coded 'load' and 'exec' values themselves), and added a new SerialPort parameter (upperCase) that can be used to force all received data to upper-case 2016-10-21 21:07:26 -07:00

5f05913036 Fixed fault generation on invalid memory accesses; PDP-11 BASIC now starts up! 2016-10-21 17:06:41 -07:00
Jeff Parsons
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
Jeff Parsons
aa2a25c5ec Minor Debugger improvements, notes, etc, while debugging the PDP-11 BASIC 2016-10-20 22:56:29 -07:00

8e2b50afe1 pdp11-device layout hack 2016-10-19 17:33:02 -07:00

d83bfcda4c More XML layout tweaks 2016-10-19 17:16:42 -07:00
Jeff Parsons
5e9891292c Added progress bar control (for the PC11 paper tape reader) 2016-10-19 14:16:14 -07:00
Jeff Parsons
bff199ee7f Fixed the PC11 component to deliver bytes at (roughly) the same rate as a physical "high speed" paper tape reader would (TODO: Add a paper tape status display) 2016-10-19 11:31:43 -07:00
Jeff Parsons
13a1dedbc7 Supoprt for tape images in the Absolute Loader format has been moved to the RAM component, so that those images can be preloaded into RAM in the same way that raw bootstrap images can; the RAM component now provides Absolute Loader image parsing as a service to other components that need it (specifically, the PC11 tape reader) 2016-10-19 11:10:38 -07:00
Jeff Parsons
69b7a682d8 Added code to parse tape data and load it directly into memory if the LOAD button is used instead of the ATTACH button 2016-10-18 20:53:26 -07:00
Jeff Parsons
6c4f8f4bb3 Code in place for parsing tape data when "load" (as opposed to "attach") is requested 2016-10-18 16:53:20 -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

6683c81299 Created dedicated getOpcode() function, replaced getPCWord() 2016-10-18 10:50:05 -07:00

Jeff Parsons
961dce8f78 Added PC11 support for loading tapes remotely 2016-10-17 18:22:42 -07:00

ed24094683 Lots of tweaks in advance of PDPjs support for loading tape files 2016-10-17 15:19:01 -07:00
Jeff Parsons
5f3694133a Updated READMEs regarding RAM image support 2016-10-17 11:18:18 -07:00
Jeff Parsons
980c2ac5ab Updated PC8080 and PDPjs to support RAM images, eliminating the need for the old "writable ROM" kludge; RAM images can include their own load and exec addresses as part of the JSON file, but the RAM component can provide explicit overrides (if no load address is specified either way, the default load address is the starting RAM address) 2016-10-17 11:01:32 -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
Jeff Parsons
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
Jeff Parsons
342746f2bc Added a PDP-11 "server array" test page 2016-10-14 11:06:33 -07:00
Jeff Parsons
a0f7b85bdd Removed an HTML template hack (should only affect the Node environment) 2016-10-14 09:41:38 -07:00
Jeff Parsons
b1f8fca2d9 Re-enabled source maps, at least for the PDP-11 emulators (for now) 2016-10-14 09:30:17 -07:00
Jeff Parsons
854b40c419 Cleaned up PDP-11/70 configs 2016-10-13 16:35:10 -07:00
Jeff Parsons
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
