a88e2d7b39 Fixed the frequency of PDP-11 display updates 2016-11-07 18:30:33 -08:00
Jeff
eb3b38a5ad Fixed XXDP disk boot (haven't tried any tests yet, but it's still good progress) 2016-11-07 17:20:53 -08:00
Jeff
8188554875 Fixed the fallback logic for IOPAGE ranges where only byte handlers exist (ie, the readROMByte() case) 2016-11-06 09:48:12 -08:00
Jeff
9e00cd4dad Attempted to make switches more "touch-friendly" 2016-11-05 15:12:52 -07:00
Jeff
71546f1ed5 Fixed incorrect RL11 addresses 2016-11-05 12:45:54 -07:00
Jeff
c67176eab0 Added the ability to install external ROMs (eg, M9312 ROM images) into the IOPAGE 2016-11-05 12:01:56 -07:00
Jeff
0cf11c0b01 Fixed the memory clear "toggle-in", by returning the correct amount of installed RAM, and passing properly masked addresses to all the I/O handlers 2016-11-04 17:09:50 -07:00
Jeff
a7a44a8288 Cleaned up the PDP-11 updateDisplay(s) code, and removed the update hack inside the WAIT instruction; display updates now occur in sync with the machine's 60Hz clock 2016-11-04 13:35:20 -07:00
Jeff
0d11d279bb Changed SDR and SAR register references to PDR and PAR, which seems in keeping with more of DEC's own literature 2016-11-03 17:19:15 -07:00
Jeff
3b88e4c53c Memory can now be explicitly "zeroed" with any byte pattern (but the default is still zero); note that memory blocks are still always zero-initialized when first created 2016-11-03 15:50:19 -07:00
Jeff
97de321daa Fixed zeroMemory() to properly zero any block(s) that originally underlaid the IOPAGE block(s), rather than trying to zero the IOPAGE block itself (which would be a bad idea) 2016-11-03 15:36:37 -07:00
Jeff
d67e848973 Changed 11/70 machines to allocate RAM as a single chunk, and updated the 11/70 page on toggle-ins (/devices/pdp11/machine/1170/panel/debugger/README.md) 2016-11-03 14:42:35 -07:00
Jeff
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
Jeff
0afab359ad The memory management toggle-in passes (see /devices/pdp11/machine/1170/panel/debugger) 2016-11-02 21:20:04 -07:00
Jeff
b3bf213cd9 Enable the Debugger to get/set front panel switches as register SW 2016-11-02 19:41:29 -07:00
Jeff
d5c7bf0b5d More Front Panel improvements 2016-11-02 13:35:50 -07:00
Jeff
caf0a728f8 More PDP-11 front panel functionality 2016-11-01 19:02:06 -07:00
Jeff
99af96a113 Added paper tape reader (PC11) to more machine configs 2016-10-31 12:56:24 -07:00
Jeff
daefc2992c Attempted to clean up mapUnibus() and bus-related faults; how well or ill-advised these changes are remains to be seen 2016-10-31 12:44:29 -07:00
Jeff
96ad4ec37e Lots of work to try to bring the new RL11 component up to snuff 2016-10-29 11:32:31 -07:00
Jeff
04be27b47b Added some RL11 register definitions 2016-10-25 14:40:33 -07:00
Jeff Parsons
9e480d7574 Added new RL11 component (work-in-progress) 2016-10-24 16:28:48 -07:00
Jeff Parsons
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
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
Jeff Parsons
d0618c34bc Added more PDP-11 paper tape resources 2016-10-23 00:43:20 -07:00
Jeff Parsons
89dc2660f1 Added more PDP-11 paper tape resources 2016-10-22 21:57:45 -07:00
Jeff Parsons
5d5629c27b More README updates, particularly in regard to DEC's Absolute Loader 2016-10-22 14:21:33 -07:00
Jeff Parsons
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
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
Jeff Parsons
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
Jeff Parsons
7beaf7ca7b More README updates 2016-10-20 15:32:37 -07:00
Jeff Parsons
21d91cbcfa Fixed the components.xsl for PDPjs machines, and added more instructions, resource links, etc, for the PDP-11 demo machines 2016-10-20 15:16:22 -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
Jeff Parsons
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
Jeff Parsons
fbb36c1d1b Updated PDP-11 READMEs 2016-10-18 12:03:23 -07:00
Jeff Parsons
6683c81299 Created dedicated getOpcode() function, replaced getPCWord() 2016-10-18 10:50:05 -07:00
Jeff Parsons
599228db46 Assorted PC11 tape loading fixes 2016-10-18 10:30:34 -07:00
Jeff Parsons
961dce8f78 Added PC11 support for loading tapes remotely 2016-10-17 18:22:42 -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
Jeff Parsons
d928bef562 Register PC11 I/O handlers 2016-10-15 17:54:45 -07:00
Jeff Parsons
6bec38acb4 Updated READMEs 2016-10-15 17:13:43 -07:00
Jeff Parsons
0f4cbd6e7b Added my first PDP-11 add-on device component (PC11) 2016-10-15 16:32:59 -07:00
