- Nope. To be honest, if you have a newer monochrome adapter (the ones that
- use VVLSI instead of TTL), Windows video is just about as fast as you can
- make it. The older (including the original) Herc cards are slower because
- of the technology/memory/circuitry used in the cards--but even so, herc
- cards are usually more than four times faster. Why, you ask? Simple:
- Monochrome graphics cards only have to move 720x320 pixels that have only
- two states: on or off. A VGA card has to do 640x480x16, an SVGA has to
- do 640x480x256, 800x600x16 (or 256), or 1024x768x16 (or 256)--there is
- much much more junk to shove across the bus. SVGA is probably the slowest
- of the slow: in order to fit the 256K, 512K, or one Meg of video RAM into
- a mappable area, SVGA's employ a rather elaborate planing scheme (mappable
- pages) which also add to speed deficiency.
-
- The problem with Monochrome graphics/Windows is that Windows tends to
- try to "dither" colors to achieve a rudimentary greyscale... this cuts down
- the overall resolution so that some Windows Apps cannot fit on the desktop
- at all (I'm thinking about Corel Draw here). Others work simply mahvelous
- (Winword 2.0 and Excel 4.0)... but appear to be slow because the system
- I'm running them on is slow.

- Hear Hear! RAM is probably the best way to increase speed (next to
- purchasing a 486/50, of course). I've also found that Smartdrv.sys
- with sufficient RAM also adds immensely to Windows efficiency.

- If GUI isn't necessary, this is a good alternative. Using Word 5.5 versus
- WordWin is always viable, using Quatro Pro instead of Excel 4.0 works well
- too. But if you need particular applications because you really NEED them,
- a 386sx-16 should work just fine until you can afford to get something
- better.
