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

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
64845d782f Fixed a tiny oversight in buildFileTable() when using a 320Kb diskette formatted by DOS 1.10 2016-10-28 09:46:29 -07:00
Jeff
88b485d094 Added a variety of checks and automatic repairs to DiskDump, aimed primarily at issues I've come across with pre-DOS 2.0 diskettes (eg, diskettes without BPBs, like 160Kb diskettes from DOS 1.0 and 320Kb diskettes from DOS 1.1) 2016-10-27 17:59:20 -07:00
Jeff
4132668bb2 Added missing @param 2016-10-26 13:26:46 -07:00

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

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

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

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

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
