The VT100 screen displays 800 dots per horizontal scan, and a total of 240 horizontal scans, and by default,
it uses a 10x10 character cell, for a total of 80 columns and 24 rows of characters.
Ordinarily, the VT100 screen displays 800 dots per horizontal scan, and a total of 240 horizontal scans, and by default,
it uses a 10x10 character cell, for a total of 80 columns and 24 rows of characters. However, in 132-column mode, it
uses a 9x10 character cell instead, and assuming no AVO expansion card is present, there is only enough screen RAM available
for 14 rows of characters; this implies a total of 1188 dots displayed per horizontal scan, and a total of only 140 horizontal
scans. This means we will have to dynamically reallocate the buffer display context whenever the horizontal dimensions change
(ie, from 800 to 1188, or from 1188 back to 800).
For optimum scaling, I would normally define the virtual screen size using multiples of the VT100's "dot" dimensions;
eg, 1600x960 (a horizontal multiplier of 2 and a vertical multiplier of 4). However, that would give us a virtual screen
aspect ratio of 1.67, which is less than the (apparent) 2.0 aspect ratio of a physical screen, so I've changed the test
machine's screen dimensions to 1600x800.
aspect ratio of 1.67, which is less than the (apparent) 2.0 aspect ratio of a physical VT100 screen, so I've changed the
test machine's screen dimensions to 1600x800.
Regarding physical dimensions, a VT100 screen measures 12 inches diagonally, and in 80-column mode, characters measure
2.0mm x 3.35mm (in 132-column mode, they measure 1.3mm x 3.35mm). This means that the text area of the screen is roughly

* 0 0 0 0 0 0 0 0 <== 00 from offset 0x0008
* 0 0 0 0 0 0 0 0 <== 00 from offset 0x0009

*
* In the second 2K chunk, we observe that the last two bytes of every font cell definition are zero;
* this confirms our understanding that MDA font cell size is 8x14.
*
* Finally, there's the issue of screen cell size, which is actually 9x14 on the MDA. We compensate for that
* by building a 9x14 font, even though there's only 8x14 bits of data. As http://www.seasip.info/VintagePC/mda.html
* explains:
*
* "For characters C0h-DFh, the ninth pixel column is a duplicate of the eighth; for others, it's blank."
*
* This last point is confirmed by "The IBM Personal Computer From The Inside Out", p.295:
*
* "Another unique feature of the monochrome adapter is a set of line-drawing and area-fill characters
* that give continuous lines and filled areas. This is unusual for a display with a 9x14 character box
* because the character generator provides a row only eight dots wide. On most displays, a blank 9th
* dot is then inserted between characters. On the monochrome display, there is circuitry that duplicates
* the 8th dot into the 9th dot position for characters whose ASCII codes are 0xB0 [sic] through 0xDF."
*
* However, the above text is mistaken about the start of the range. While there ARE line-drawing characters
* in the range 0xB0-0xBF, none of them extend all the way to the right edge; IBM carefully segregated them.
* And in fact, characters 0xB0-0xB2 contain hash patterns that you would NOT want extended into the 9th column.
*
* The CGA font is part of the same ROM. In fact, there are TWO CGA fonts in the ROM: a thin 5x7 "single dot"
* font located at offset 0x1000, and a thick 7x7 "double dot" font at offset 0x1800. The latter is the default
* font, unless overridden by a jumper setting on the CGA card, so it is our default CGA font as well (although
* someday we may provide a virtual jumper setting that allows you to select the thinner font).
*
* The first offset we must pass to setFontData() is the offset of the CGA font; we choose the thicker "double dot"
* CGA font at 0x1800 (which was the PC's default font as well), instead of the thinner "single dot" font at 0x1000.
* The second offset is for the MDA font.
