f6fe72f43f Cleaned up the SerialPort header a bit 2017-08-08 17:12:20 -07:00

bf5e1faf67 Changed X86CPU.reset() to not stop the CPU on a RESET (you can still force HALT after RESET by simply halting the machine manually before clicking RESET); moreover, by not calling stopCPU() in the X86CPU.reset() handler, we avoid problems in the CPU's speed recalculation logic (for example, if you repeatedly clicked RESET on a running machine, speed variables would get out of sync) 2017-08-07 19:21:15 -07:00

a3c252bf99 Cleaned up browser support for full-screen and pointer-locking in the Video component, and reduced the default scale factor for mouse movement events from 1.0 to 0.5, since modern screens are generally much higher resolution 2017-08-02 10:37:45 -07:00
Jeff Parsons
072b8fa2df Laid the groundwork for bring PCx86 up-to-date with timer functionality matching PC8080 and PDPjs (new timer services added) 2017-08-01 14:26:52 -07:00

Jeff
fe74e12e40 Added the *scaleMouse* property so that host mouse coordinates can undergo an optional scaling transformation (default is 1.0) 2017-07-24 18:47:10 -07:00
Jeff
6a3f7f4a5d Added support for segment wrap-around in 8086/8088 real-mode (all stack operations, instruction fetches, and operand accesses should wrap now); real-mode wrap-around on newer processors should trigger a GP fault instead 2017-07-23 14:59:26 -07:00
Jeff
a85662632c Fixed serial port transmitter interrupts, and added a new blog post (RetroReview: SPEEDUP) 2017-07-22 23:08:46 -07:00

Jeff
d8cdebae3b Fixed full-screen support (it was broken in the commit that enabled flicker support), and more tweaks to the stack limit checks in the pushWord() and popWord() functions 2017-07-20 20:00:31 -07:00
Jeff
fb493d09ac Handle wrap-around for 16-bit real-mode POPs as well 2017-07-20 12:13:08 -07:00
Jeff
a0951aeea9 Replaced the previous temporary PUSH fix with a permanent fix, along with 8086/8088 support for 16-bit pushes that wrap around 64K boundaries (must be done with two discrete byte operations) 2017-07-20 11:25:58 -07:00
Jeff Parsons
308bd75af4 Added a temporary fix to PUSH operations to ensure that 16-bit pushes wrap around 64K boundaries (TODO: a 16-bit PUSH at offset 0x0001 or a POP at offset 0xFFFF must either wrap or fault as appropriate) 2017-07-19 23:24:18 -07:00

6c6f28c1ef Fixed PCx86 to recover from situations where a page entered an "unloaded" state but wasn't actually unloaded. 2017-07-19 14:57:19 -07:00
Jeff Parsons
8035a95cf9 The PCSIG08 README needed to use a "raw" link rather than a Markdown link, so that it could set the "download" attribute on the link, preventing the page's "onbeforeunload" handler from firing (which would otherwise shutdown any machines on the page) 2017-07-19 14:13:29 -07:00
Jeff Parsons

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

Jeff Parsons
e33adffbf4 Switched from mouse event clientX and clientY to screenX and screenY (will it make any difference on high DPI screens? I don't know...) 2017-07-05 23:01:50 -07:00

Jeff Parsons
