There are four groups of connectors (Line A, Line B, RGB/Component, and Ext Sync), and each group should be treated as a whole. As it's a monitor, I assume you have an "out" for each "in", and the "out" is just connected to the corresponding "in" (because "out" otherwise doesn't make sense for a monitor). You'...

The 130XE has two display outputs, as you've probably already seen. The easiest one to use is a VHF/UHF TV output, which should go to a TV that supports analogue TV standards. It should be relatively easy to find a TV antenna cable; you can combine it with the output of a set-top box, if needed, with a UHF Y adapter. You'll need to tune the TV to ...

No. The Mac SE vertical and horizontal scan frequencies (designed into both the CRT yoke and the analog sweep generator circuits) are different from NTSC (and PAL) composite timing. And the Mac SE analog board requires separate vertical and horizontal sync inputs, not just a video signal. The analog board sync inputs need to be at TTL voltage levels, ...

No, for many reasons. The yellow connector that you are talking about is called composite video. It's called "composite" because it combines several signals: vertical synchronization, horizontal synchronization, blanking, luminance (the black-white part), and chrominance (the color part). No model of Macintosh bothered to combine these signals, ...

So when I have a Composite Cable with Video/L/R means, I put the cable into Video IN (Line A) and Audio In (Line A+B)? It looks to be mono audio only so you can either get an adapter that connects left and right audio together or run your stereo audio through a separate amplifier. Either Audio A or B (but not both) will be selected along with the ...

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-...

An unmodified Amiga 500 provides two outputs: analogue and digital RGB through its DB23M connector monochrome composite through its RCA connector Colour encoding is identical in both PAL and NTSC variants on the RGB output, and not present on the RCA connector, so the vast majority of screens with the corresponding inputs will work fine with either (they ...

Partial answer: Having looked at the manual, the only connection is a two-wire cable to video aux. They also say that any composite monitor connected to the internal Apple video must be NTSC composite compatible. As the Apple 6502 keeps running, I would assume they have the Apple display a black screen, and then sync up and overlay their own pixel outputs on ...

The Atari XL/XE machines (“all but 400, NTSC 600XL, SECAM 800XL/130XE/XEgs”, according to the FAQ) have a video port broadly compatible with the Commodore 64. The connector (180° 5-pin DIN) and important pins are the same: 2 — Ground; 3 — Audio Output; 4 — Composite Video. So unless you have a SECAM 130XE, a cable described on ebay something like “...

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 ...
