Programming the PC Speaker, by Phil Inch: part 1, part 2 (includes a very detailed explanation of how to play back PCM audio on the PC speaker, and why it works) Bleeper Music Maker A freeware to use the PC speaker to make music (superseded by BaWaMI)
Close-up of a sound card PCB, showing electrolytic capacitors, SMT capacitors and resistors, and a YAC512 two-channel 16-bit DAC. [1] The integrated circuit on the left is a 3403 single power supply quad operational amplifier. Sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an ...
A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
The video signal path can range from six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit, 192 kHz uncompressed PCM audio. [1] A bidirectional, half-duplex auxiliary channel carries device management and device control data for the Main Link, such as VESA EDID , MCCS , and DPMS standards.
Default Amiga screen modes are directly compatible with TVs in the region in which the computer was sold, so that the user could connect the computer to a common TV if no monitor was available. In the PAL region, the Amiga could be connected directly to the standardized SCART RGB connector on the TV via an adapter cable sold by Commodore ...
The VIC-II chip was designed primarily by Albert Charpentier and Charles Winterble [1] at MOS Technology, Inc. as a successor to the MOS Technology 6560 "VIC".The team at MOS Technology had previously failed to produce two graphics chips named MOS Technology 6562 for the Commodore TOI computer, and MOS Technology 6564 for the Color PET, due to memory speed constraints.
The control signal is a square wave operating at 25 kHz, with the duty cycle determining the fan speed. 25 kHz is used to raise the sound of the signal above the range of human hearing; use of a lower frequency could produce an audible hum or whine. Typically a fan can be driven between about 30% and 100% of the rated fan speed, using a signal ...
The ATX specification requires that the power-good signal ("PWR_OK") go high no sooner than 100 ms after the power rails have stabilized, and remain high for 16 ms after loss of AC power, and fall (to less than 0.4 V) at least 1 ms before the power rails fall out of specification (to 95% of their nominal value).
