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

b1f8fca2d9 Re-enabled source maps, at least for the PDP-11 emulators (for now) 2016-10-14 09:30:17 -07:00

854b40c419 Cleaned up PDP-11/70 configs 2016-10-13 16:35:10 -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

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

58d358b51e Switching to new interrupt triggers 2016-10-12 16:40:47 -07:00

30e67a015b Fixed some idiosyncrasies involving the versioned folder names for the various emulators. Any compiled pdp*.js script (eg, pdp11.js) will be stored in the /versions/pdpjs folder, just as any compiled c1p*.js script will be stored in the /versions/c1pjs folder. Other emulators that don't use a "js" suffix in their name (eg, PCx86 and PC8080) are stored in /versions folders that mirror their names. 2016-10-11 12:19:54 -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

c69ebb7bcb Factored out mapVirtualToPhysical() calls when MMU not enabled, and fixed HALT (it actually halts the CPU now) 2016-10-07 09:49:02 -07:00
Jeff
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

21b4fe4942 Renamed PDP11js to PDPjs (mostly a cosmetic change, except for the versions directory, and less of a mouthful) 2016-10-05 17:43:46 -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

1ec60573d5 Implemented opJSR, removed more "negative address" tests (eg, in pushWord); bad addresses should result in special exceptions, not negative return values 2016-09-26 09:43:05 -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
a451bbc5bc Added another example of an I/O address handler (XCSR) 2016-09-25 15:15:06 -07:00
