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

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

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

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

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

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

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

4c63c8a97f Quick change (perhaps temporary) to update LEDs on every WAIT transition (similar to the behavior of the original pdp11.js) 2016-10-11 10:47:09 -07:00

Jeff Parsons
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
