I published, in PC TECH JOURNAL in 1985, an article about how to get
true monochrome video from a CGA (rather than the striped-looking stuff
that it normally produces). Some newer CGAs have greatly reduced the
amplitude of the stripedness (which consists of subharmonics of 3.58 MHz
intended to fool a color TV into displaying color).
