Your article in January's Cadence, on page 76, said that Panacea's DLD 386 Deluxe supported anti-aliasing. Are you sure? A client of mine that has the Diamond Speedstar Hi-Color wants to know if that would work on his similarly chip-equipped card. Thanks for any help you might provide.

Lansing, DLD386Deluxe supports antialiasing in CEG mode, but not Sierra HiColor mode. Diamond's version of DLD386 does not contain CEG support, because Diamond is not shipping CEG versions of the SpeedStar in quantity. If your customer is interested, we sell Diamond specific upgrades to DLD386Deluxe for $125. Brad Ek [Panacea Inc.]

Yes, it's done in software. The board's 256-colors are anti-aliased down to 16 colors. Isn't it amazing how software is taking over hardware? Software display-list processing, software disk-doublers (Stacker), software disk caching, software memory managers, software anti-aliasing, and in VMI's case, RenderReady software that does an effective job of fooling the eye into seeing true-color images. Regards, Ralph G.

Ralph: I don't know if I agree that software is taking over hardware… I think the software writers discovered that the more products that they have out there the more $ they will get from updates (feature or new hardware generated…). The more $ from updates, the more products you can afford to create… seems to me that the software industry is just figuring out the same >features< of planned obsolescense that the hardware industry has been using.

If I understand your reference to VMI's Render Ready software, I think you missed part of the implementation. I believe that there is custom microcode on the VMI card that translates the 2**24 possible colors of a pixel to a particular 2**8 blend in a 2×2 array. So your 1280x1024x8 card is "equivalent" to a 640x480x32 piece of hardware. But you're right, the process COULD be done totally in (host) software.
