99af96a113 Added paper tape reader (PC11) to more machine configs 2016-10-31 12:56:24 -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

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

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

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

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

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

1a1614a648 Simplify the Bus and Memory interfaces slightly, by enabling WORDBUS, which treats all word accesses as aligned; the CPU is has sole responsibility for detecting unaligned word addresses and trapping appropriatelu 2016-10-06 14:17:29 -07:00
Jeff
795d57839b Cleaned up the decoding SRCMODE and DSTMODE operands, should be less confusing now 2016-10-04 17:22:25 -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
Jeff

5b25dc91ae Let's stop on any un(re)implemented opcode for now 2016-09-26 10:02:21 -07:00
Jeff
a4613082f8 Converted all "short" references to "word", since word meant 16-bit in the PDP-11 world, and no one said short back then 2016-09-26 08:53:35 -07:00
Jeff
b28166f493 Updated Closure Compiler to v20160911, so now we have a version that supports ECMAScript 6, but I'm not going to go bonkers on ES6 features just yet; the first feature I'm going to use is support for octal and binary constants (of the form 0onnnn and 0bnnnn) 2016-09-24 16:03:57 -07:00
