The first version of Windows to support out-of-the-box DVD playback is Windows XP Media Centre Edition*, which was created specifically to target the HTPC fad that you mention, and it also has some special hardware requirements. The only mainstream versions of Windows to play DVDs without additional software were Windows Vista Home Premium and Ultimate, and ...

A standard VDC chip of the early eighties is the Motorola 6845. While originally intended not for pixel-addressable, but rather character-addressable frame buffers, it can easily be tricked into generating a pixel-adressable bitmap display (like used in many Amstrad computers)- The chip does not generate the video itself, but rather does the ghard work only ...

I'd suggest using a chain of discrete counters clocked with 4x chroma and generating a composite signal directly from that, using resistors as a crude DAC for the output stage. If e.g. you have use a two-bit DAC that can generate sync, black, and two levels above that, you could fairly easily generate 81 colors by outputting a repeating sequence of four non-...

The "Technical Descriptions" link for the Nick Chip on this Enterprise 64/128 Technical Information page is a .pdf file. Page 13 of this file seems to say that the 256-color palette uses 3 bits for red, 3 for green, and 2 for blue.

The horizontal counter increments continuously with the CRTC clock, and the vertical counter (divided into a pixel row counter and a text line counter) increments continuously with the horizontal sync pulse. The blanking and sync signals are toggled, and the counters are reset, when these counters exactly match values set in configuration registers. The ...

Short answer from memory: At the beginning of a frame the address is set to zero The address is incremented over a line for R0 (total chars aka horizontal timing) character access cycles. Only R1 (displayed characters) are visible. The address is reset after R0 character access cycles. Then the scan line counter is incremented When the scan line counter ...
