7fb74e7d0d Tweaked how the PCx86 RTC Update-in-Progress bit is set/cleared (allows SpinRite 3.1 to cleanly exit on a PC AT now) 2017-09-17 11:46:25 -07:00

2522566d16 SerialPort documentation clarifications 2017-08-25 09:15:21 -07:00
Jeff Parsons
dbaf381f9b If a SerialPort is installed, the transmitter portion of the hardware is no longer required to be connected to anything, which avoids blocking software (eg, the OS/2 kernel debugger) that uses that port; uninstalling the SerialPort would be another option, but that's no longer required 2017-08-25 08:53:58 -07:00

3d36682396 Cleaned up endBurst() and changed yieldCPU() to stop ending bursts prematurely (it only sets the new yield flag now) 2017-08-14 10:36:10 -07:00

1226392d9f Work-around to make sound for iOS devices a little more robust without having to do anything iOS-specific 2017-08-12 15:08:30 -07:00

9807bd9f15 Still not sure if all web browsers conform with the latest Web Audio properties and methods 2017-08-12 12:55:53 -07:00
Jeff Parsons
33cabfc348 Found a work-around for preventing browsers from "easing" (aka de-zippering) the sound from an oscillator when its frequency is altered; also attempted to provide a mechanism for starting the audio in response to a user-generated (eg, touchstart) event, in an effort to enable PC speaker sounds on an iPad, but iOS devices are a real pain in the butt.... 2017-08-12 12:15:24 -07:00

d8e329b12c Using some things I learned from @stevekinney today, I've tweaked the PC speaker code to no longer stop() and destroy oscillators every time the speaker is toggled off; instead, the ChipSet component now uses one oscillator for the life of the machine (created the first time the PC makes a sound) and simply zeros/sets the gain as needed. We still have the "easing" issue to deal with (whenever the PC the makes sudden changes to the frequency) and I still can't use dot names for any of the AudioContext properties (until I either update the Closure Compiler or manually add an externs file for the AudioContext interfaces). 2017-08-11 20:05:48 -07:00

8523800d8c When a key is required to dismiss a PCx86 machine diagnostics screen, make sure that key isn't also passed on to the machine 2017-08-09 12:44:54 -07:00

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
Jeff Parsons

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

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

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

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
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
