d5ddde3e41 More alert suppression changes 2017-06-22 16:34:04 -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
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

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

Jeff

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
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

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

65eb821710 Well, apparently the PDP-10 MUL instruction really DOES store the high-order word first, and it only stores the low-order word if the destination is an accumulator (weird) 2017-03-07 14:09:24 -08:00
Jeff

Jeff
3d4795bbe4 Updated the Int36 class with support for both signed 71-bit values (my original double-length format) and 70-bit values consisting of two signed 35-bit values (DEC's double-length format) 2017-03-06 15:48:31 -08:00
