less than a car which will have throughput competitive with a (shared) supermini. So i'm gonna junk the old xt and buy a 25 MHz 486 machine loaded w/memory etc. I intend to run Windows, if it doesn't limit me in some way. I intend to do image processing on 8-bit imagery using Neural Net algorithms (i.e., lots 'o' flops - correlations, array operations, statistical analysis) and i will need the CPU throughput and 256-grey-level display capability to support it. Since i have been out of touch with the PC world, i would like to solicit some advice: * I would like to get a Weitek coprocessor, but i would also like to stay with Turbo C++ (i understand 2.0 does windows - any bugs?). Can the new Tc++ gen- erate Weitek code or is there some other compiler compatible w/ Tc++ with which i can build a linkable library? * I need to display 8-bit (256-level) grey scale with a minimum of 512x640 resolution (and square pixels!). I have been told that there is an enhanced VGA mode which supports this. Which compilers and graphics cards are able to work in this mode, if any? I would like to stay as "mainstream" as possible, e.g. paradise card, turbo c. * I will eventually need to build a user interface and would prefer to make it portable. Thus i'd like to hear reccommendations/experiences concerning X-windows packages running under MS windows. Any comments on mouse support would also be helpful. I think that there must be other NN/IP researchers like myself who would find this info valuable. Please respond to this by e-mail and i will summarize on the appropriate topics. this is especially important since i will be posting this to several PC HW, PC SW, and ANN topics and might miss your response if you just posted it. I will credit all responses in my summary. Thank you all in advance! Walter Alden Tackett tackett@ipla01.hac.com sahtirn@ipla01.hac.com

Since the physical aspect ratio of most VGA monitors is 4:3 you will either use that ratio or skip using a bunch of your screen. There are companys which make vertical greyscale monitors (so called "full page" monitors) but they are pricey, like many things which are sold in niche markets. It would probably be cheaper to buy a 1024x768 card, a standard VGA (color) monitor, and use part of the screen. You can get monitors up to 20 inch, although you better have deep pockets. at the 14-16 inch size it's pretty affordable, and you can buy from established companies. Ballpark figures: 1024x768x256 card $ 200 (ex: SWAN) 14 inch monitor $ 600 (ex: NEC 3D non-multisync cheaper) 16 inch monitor $ 900 (ex: NEC 4D) 20 inch monitor $1900 (ex: NEC 5D) These brands are for example, but they represent stuff which has been selected at work for technical reasons. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
