c4a8d66027 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 13:35:50 -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

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

d4d3448fd5 Cleaned up how components print messages and how the Computer component overrides their notice/print/println methods (in preparation for new Computer overrides) 2017-06-28 10:53:44 -07:00

2cb0be42f0 Setting the stage for a resource status update mechanism 2017-06-27 16:01:00 -07:00

7457e4e44f Changed the default page "exit" event handler from "onunload" to "pagehide" for iOS; hopefully, auto-resume machines will work better on mobile devices with that change 2017-06-25 08:32:27 -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

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
4e0d3d46da Fixed root directory check to ensure we don't select a disk format with too few root directory entries 2017-06-19 18:12:33 -07:00

20f8bdf141 Added more info about DOS 2.0 BPBs 2017-06-01 16:42:46 -07:00
Jeff Parsons
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
d4c12c8c7a Fixed the PDP-10 BLT instruction 2017-04-05 11:32:16 -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
470bd1d69e Fixed unary operators applied to bracketed expressions 2017-04-01 21:11:01 -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
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
1d1ac0cb7b The shared expression parser now adapts to the (critically) different precedence of MACRO-10 operators 2017-03-30 11:53:21 -07:00
Jeff
d5c48df9bc Added support for MACRO-10 literal collapsing; it's not super-aggressive, but it's more than adequate for what DEC's diagnostics require 2017-03-28 15:22:17 -07:00
Jeff
d13e7a5faf The expression parser now allows spaces inside expressions (a relaxation for certain MACRO-10 typos; eg, "- 1" where "-1" was expected) 2017-03-28 12:01:06 -07:00
Jeff
b2a6a06908 Fixed parsing of expressions with spaces 2017-03-28 09:17:09 -07:00
Jeff
6ad35d2d17 Added the ^L MACRO-10 unary zero-bit-counting operator, and updated the last blog post with expression parser differences (eg, interpretation of numbers with a decimal point) 2017-03-21 17:40:37 -07:00
Jeff
127ddb88b4 Added the unary + operator, and cleaned up the display of values from the expression parser 2017-03-21 12:47:43 -07:00
Jeff
a42a261cca README fixes 2017-03-20 15:33:01 -07:00
Jeff
a6021441c3 Fixed the signed truncation of 36-bit values (so that "-34,359,738,368. - 1" correctly produces "34359738367. aka 0o377777777777"), added the proper the right-to-left parsing of unary operators (all two of them: negate and complement), changed the PDP-10 disassembler to honor the selected base when displaying opcodes, and updated all the number-to-string conversions to select an appropriate number of digits when rendering values without a specified number of digits. 2017-03-20 13:34:25 -07:00
Jeff
5d2a1ed16b Fixed limits on MACRO-10 ASCII and SIXBIT constants 2017-03-19 14:13:24 -07:00
Jeff
4cce2177f4 The recursive MACRO-10 test case (MACTEST1.MAC) found in the June 1972 MACRO-10 manual passes now 2017-03-19 14:03:49 -07:00

01e9bcf0fe Fixed multiline ASCIZ MACRO-10 pseudo-op, and expressions with binary shift suffixes finally evaluate correctly in parseExpression() 2017-03-16 16:50:47 -07:00
Jeff
ab0dccd866 Added MACRO-10 work-arounds for numeric values with embedded binary shift counts 2017-03-16 12:45:19 -07:00
