ec438be5c9 Fixed old, longstanding, and surprisingly bad bug in cleanMemory() for all machine implementations 2017-07-12 21:02:30 -07:00
Jeff Parsons
9e149dda6a Added support for a new "flicker" PCx86 Video property that simulates good old-fashioned CGA flicker -- don't leave home without it! 2017-07-12 16:22:26 -07:00

4577092917 Standardized on autoMount (vs. automount) and created compiled version of the PCSIG08 disk manifest (because it's huge) 2017-07-11 19:10:05 -07:00
Jeff Parsons
0bbf720c35 Changed DiskDump to deal better with disk images that are physically larger than the disk's logical file system (specifically, 320Kb FAT images inside 360Kb disk images, and 160Kb FAT images inside 180Kb disk images); the Lotus 1-2-3 v1.0a disks I dumped from my personal collection are the perfect example. 2017-07-04 13:37:58 -07:00

7768f27e40 Added an Modula-2 demo page and a new blog post on the 1984 FantasyLand EGA demo and an EGATEST program written in Modula-2 2017-07-03 22:37:40 -07:00

51f8440e9b More diagnostic output improvements 2017-06-28 17:51:15 -07:00
Jeff Parsons
ea82dfec93 A machine's screen can now be used to display initialization (diagnostic) messages, up until the Computer component is ready to power/start the CPU, at which point control of the screen reverts to the Video component 2017-06-28 16:24:33 -07:00

2cb0be42f0 Setting the stage for a resource status update mechanism 2017-06-27 16:01:00 -07:00
Jeff Parsons
0ec54f6da4 Started work on v1.35.2 2017-06-27 12:01:19 -07:00
Jeff Parsons
49f25f682d Assorted application updates 2017-06-25 09:16:08 -07:00
Jeff Parsons
113201fdb4 Added a cleaner solution for string replacement woes (ie, use Str.replace() instead of applying replace(/\$/g, "$$$$") to replacement strings) 2017-06-23 11:56:14 -07:00
Jeff Parsons
991e924d01 Added support for special autoType sequences (eg, $date and $time, which generate current date and time strings accepted by the PC-DOS date and time prompts) 2017-06-23 09:39:40 -07:00
Jeff Parsons
a16f0586f4 More alert suppression changes 2017-06-22 16:36:51 -07:00
Jeff Parsons
1ce03810d3 Added support for (attempting to) suppress alerts that are meaningless if the user has aborted a machine by exiting the page before it was done loading 2017-06-22 15:53:34 -07:00
Jeff Parsons
9626fed7c2 Got rid of more app-specific demo machines (eg, DONKEY and WIN101); demos like that are more properly located in either the /apps or /disks folders (not /devices) 2017-06-22 12:03:52 -07:00
Jeff Parsons
6fd2a3bcb6 Started work on v1.35.1 2017-06-21 11:18:02 -07:00

f0f3d8fa42 Added v1.35.0 files 2017-06-15 15:12:30 -07:00

3e1aa196bd Added an empty 10Mb disk image formatted by PC-DOS 2.0 (currently used by one machine: 5160/cga/640kb); also fixed some issues uncovered in the process of creating the disk image (eg, a bug in the HDC's save logic when no image has been loaded), and made some fixes and optimizations in DiskDump 2017-06-01 15:32:17 -07:00
Jeff
ea95de4939 Fixed (or rather, band-aided) a MACRO-10 regression assembling the nested macro test (/apps/pdp10/tests/macro10/TEST.MAC) 2017-04-05 20:42:44 -07:00
Jeff
5f72f1627f Updated the first PDP-10 reliability test (DAKBA) 2017-04-05 16:33:16 -07:00
Jeff
6bd24c5347 Fixed how index operands are assembled into PDP-10 instructions, which was an unexpectedly convoluted process (they are NOT masked to 4 bits, shifted left 18 bits, and OR'ed into the opcode; instead, they are computed as a 36-bit value whose left and right 18-bit halves are swapped and then ADDED to the opcode, which means that an instruction encoded with indexing may not end up using indexing at all, depending on where all those bits fall) 2017-04-05 12:38:36 -07:00
Jeff
d4c12c8c7a Fixed the PDP-10 BLT instruction 2017-04-05 11:32:16 -07:00
Jeff
7e1fc5586e Added a minor improvement to the simplistic MACRO-10 fixup support in PDPjs 2017-04-04 16:34:03 -07:00
Jeff
427e6afdb8 Fixed OPDEF opcode generation (improper use of bitwise operators) 2017-04-04 11:26:49 -07:00
Jeff
d28d1ee940 Added a few PDP-10 byte pointer fixes, along with the ability to pass MACRO-10 text directly into the MACRO-10 assembler (use the Debugger's "as" command) 2017-04-04 10:42:41 -07:00
Jeff
38f709bb7a Corrected a few expression parser changes that had adversely affected other debuggers (eg, PCx86) 2017-04-03 16:27:52 -07:00
Jeff
09dc4dcb9a Lots of MACRO-10 improvements, DAKAM now assembles (but does not pass) 2017-04-03 16:10:08 -07:00
Jeff
3fb3f44384 Made a tiny 72-bit division optimization 2017-04-02 11:43:54 -07:00
Jeff
01550cc95e Well, that was brutal, but ALL the PDP-10 DAKAL multiplication and division tests FINALLY pass 2017-04-02 10:35:59 -07:00
Jeff
493ae6c310 I *think* all the PDP-10 DAKAL multiplication tests pass now. Division tests, alas, are a different story. 2017-04-01 23:06:41 -07:00
Jeff
470bd1d69e Fixed unary operators applied to bracketed expressions 2017-04-01 21:11:01 -07:00
Jeff
1a8c1306d4 Fixed 36-bit multiplication results in cases of overflow 2017-04-01 15:14:27 -07:00
Jeff
75b9a9c2ba Fixed the Debugger's arithmetic truncation function (truncate()) 2017-04-01 14:36:39 -07:00
Jeff
1711393755 Fixed 36-bit multiplication in the expression parser so that, within the PDP-10 environment, it produces the same 36-bit results that a PDP-10 would produce (important for MACRO-10 compatibility) 2017-04-01 00:43:44 -07:00
Jeff
26de8bbb1a Added another PDP-10 KA10 diagnostic (DAKAL) 2017-03-31 19:52:11 -07:00
Jeff
1786b3bf31 Fixed some regressions in MACRO-10 support (all the KA10 diagnostics archived so far assemble and pass again) 2017-03-31 18:43:13 -07:00
Jeff
afd621dc79 Updated the PDP-10 DAKAK diagnostic page, and verified the ability to assemble (but not run) all the original DAKAK source files, after making further improvements to the built-in MACRO-10 Mini-Assembler 2017-03-31 16:32:37 -07:00
Jeff
e7988597c5 Changed the remainder operator from '%' to '^/', mainly because '%' must be allowed in MACRO-10 symbols instead, but also because '%' led one to believe it was a "mod" operator (it wasn't); added IFDEF support to the MACRO-10 Mini-Assembler; updated the Debugger's assemble command to recognize filenames with "KLM" extensions, too. 2017-03-31 09:37:38 -07:00
Jeff
71e2ecb5cb PDP-10 "DAKAK" multiplication diagnostic passes 2017-03-31 08:14:56 -07:00
Jeff
307517fd76 PDP-10 multiply diagnostic testing finally underway; fixed one bug related to the KA10 (not that anyone really cares anymore) 2017-03-30 23:46:01 -07:00
Jeff
90ae3f1db8 Fixed the signed 8-bit calculation of all PDP-10 shift/rotate counts; diagnostic DAKAJ now passes 2017-03-30 17:31:13 -07:00
Jeff
881da5b19c Added another PDP-10 diagnostic (DAKAJ), which in turn required some more MACRO-10 support (eg, macro parameters with backslashes) 2017-03-30 16:04:00 -07:00
Jeff
3f06667597 Fixed/simplified opASH() a bit; it wasn't preserving the sign bit in all cases, and converting the input from unsigned to signed and back again was more confusing than helpful 2017-03-30 14:49:49 -07:00
