- *
- * TODO:
- * - Should simulate a Unix kernel panic and reboot.
- * - Making various boot noises would be fun, too.
- * - Maybe scatter some random bits across the screen,
- * to simulate corruption of video ram?
- * - Should randomize the various hex numbers printed.

+ * Simulate various Apple II crashes. The memory map encouraged many
+ * programs to use the primary hi-res video page for various storage,
+ * and the secondary hi-res page for active display. When it crashed
+ * into Applesoft or the monitor, it would revert to the primary page
+ * and you'd see memory garbage on the screen. Also, it was common for
+ * copy-protected games to use the primary text page for important
+ * code, because that made it really hard to reverse-engineer them. The
+ * result often looked like what this generates.
+ *
+ * Sometimes an imaginary user types some of the standard commands to
+ * recover from crashes. You can turn off BSOD*apple2SimulateUser to
+ * prevent this.
+ *
+ * It simulates the following characteristics of standard television
+ * monitors:
+ *
+ * - Realistic rendering of a composite video signal
+ * - Compression & brightening on the right, as the scan gets truncated
+ * because of saturation in the flyback transformer
+ * - Blooming of the picture dependent on brightness
+ * - Overscan, cutting off a few pixels on the left side.
+ * - Colored text in mixed graphics/text modes
+ *
+ * It's amazing how much it makes your high-end monitor look like at

+ * in curly script on it and you'd be set.

+/*
+ * Implementation notes:
+ *
+ * There are roughly 3 parts to this hack:
+ *
+ * - emulation of A2 Basic and Monitor. Not much more than printing random
+ * plausible messages. Here we work in the A2 memory space.
+ *
+ * - emulation of the A2's video output section, which shifted bits out of main
+ * memory at a 14 MHz dot clock rate, sort of. You could only read one byte
+ * per MHz, so there were various schemes for turning 8 bits into 14 screen
+ * pixels.
+ *
+ * - simulation of an NTSC television, which turned the bits into colored
+ * graphics and text.
+ *
+ * The A2 had 3 display modes: text, lores, and hires. Text was 40x24, and it
+ * disabled color in the TV. Lores gave you 40x48 graphics blocks, using the
+ * same memory as the text screen. Each could be one of 16 colors. Hires gave
+ * you 280x192 pixels. Odd pixels were blue or purple, and even pixels were
+ * orange or green depending on the setting of the high bit in each byte.
+ *
+ * The graphics modes could also have 4 lines of text at the bottom. This was
+ * fairly unreadable if you had a color monitor.
+ *
+ * Each mode had 2 different screens using different memory space. In hires
+ * mode this was sometimes used for double buffering, but more often the lower
+ * screen was full of code/data and the upper screen was used for display, so
+ * you got random garbage on the screen.
+ *
+ * In DirectColor or TrueColor modes, it generates pixel values directly from
+ * RGB values it calculates across each scan line. In PseudoColor mode, it
+ * consider each possible pattern of 5 preceding bit values in each possible
+ * position modulo 4 and allocates a color for each. A few things, like the
+ * brightening on the right side as the horizontal trace slows down, aren't
+ * done in PseudoColor.
+ *
+ * The text font is based on X's standard 6x10 font, with a few tweaks like
+ * putting a slash across the zero.
+ *
+ * I'd like to add a bit of visible retrace, but it conflicts with being able
+ * to bitcopy the image when fast scrolling. After another couple of CPU
+ * generations, we could probably regenerate the whole image from scratch every
+ * time. On a P4 2 GHz it can manage this fine for blinking text, but scrolling
+ * looks too slow.

+ crank the horizontal width down in order to not lose the right few
