A while ago we tried to hook up the NEC Multi to an AT&T Targa 24 board and one of the sync signals from the board was not strong enough for the NEC monitor to pick up. The fundamental difference between the EGA and the VGA is that the EGA is TTL and the VGA is analog. The NEC works fine with the PGA (which is what I assume it was designed for) but not with all analog video sources. This is what got corected (I think) in the nec II or + or something like that. I hope I cleared things up as opposed to clouding the issue. Ephram Cohen ephram@violet.berkeley.edu

Actually, the problem is not either with the resolution or with the number of colors, but the fact that in 480 line modes the PS/2 monitors expect 2 negative sync signals, in 400 line mode, one positive and the other negative, and in 350 line modes one negative and the other positive -- some older multisync monitors don't like these rather arbitrary setups. Most work best with a positive H-sync and a negative V-sync (as in EGA-350 line modes). The Taxan multi frequency monitor is the most versatile in the respect that I am aware of, by letting you adjust the screen for each of the 4 sync combinations -- you can make it a PS/2 monitor clone if you want, you can make it work with older video boards too. Its a shame I don't like its colors. . . Charles Marslett STB Systems, Inc. chasm@killer.UUCP ============================================================================

I am trying to decide whether it is worth buying a VGA board for a 386 AT. I would appreciate any suggestions about which are best, particularly from people who have experiences (good or bad) to report. There are also several EGA boards which claim to support several VGA modes, and I wonder if these are worth considering. The basic goal here is to get high resolution color with a modest price. Please email me your responses and I will summarize for the net. Thanks... Rich Goldschmidt uunet!rlgvax!golds or sun!sundc!rlgvax!golds or ARPA: rlgvax!golds@uunet.uu.net

Having recently purchased a VGA card that I am very happy with. I would
like to get some conversation going suggesting good books and places to
get information on programming with the VGA card. Anybody know anything
yet?
For all those wondering though, I am using a Everex EVGA card and I would
recommend this card to everyone that is looking to purchase one. I have
had very little trouble with mine, which is not what I've heard about
paradise or vega cards. If you are looking for VGA card, look only to
everex to supply your needs. (Not even a paid advertisement) I should
mention though that I have no direct experience with Vega or Paradise or
any other VGA card so my recommendation is based on the trouble free
experiences I've had with the Everex card.
Again though, any good places for VGA information?
Also, let's start getting some VGA information flowing.

It is published by Microsoft Press and costs $24.95. When I had to port a major graphics application to VGA, this is the book I turned to. It covers more than just VGA, and has a wealth of source coded routines. It is very well written.

Here are two books that look pretty good, from the little bit that I've seen: EVA/VGA A Programmer's Reference Guide by Bradley Dyck Kliewer Intertext Publications/McGraw-Hill Programmer's Guide to PC & PS/2 Video Systems by Richard Wilton Microsoft Press The first book is more hardware-oriented -- useful if you're bypassing the BIOS and writing your own drivers. The second book has may be more than you need. It covers CGA (barf) and all Hercules cards, has a complete summary of all BIOS calls, has lots of BIOS examples, and quite a few examples of applications (how to draw lines, circles, graphics text, filled regions, etc.). -- Mark Alexander (UUCP: amdahl!drivax!alexande) "Bob-ism: the Faith that changes to meet YOUR needs." --Bob (as heard on PHC)

Could somebody out there please explain why IBM did not provide double buffering with the VGA 320x200 256 color mode? I spend my spare time writing arcade action games and other smooth animations but without double buffering I might as well stick to EGA 320x200. Any opinions / remarks welcome at schilder@uva.nl
