This device (HAM-E) fits between the RGB port and the monitor on an A500 up to A2500 (A3000 de-interlaced would probably confuse the hell out of it). From what I've read, its waits for a certain signaling line at the top of a screen (first scanline) and then begins processing the picture to give you a HAM display with a 256 color register from a palette of ? (a lot). If this special scanline isn't present, HAM-E just passes the normal video through, resuling in a system that can co-exist with your workbench and so on. My impressions of DCTV from magazine articles (what little there has been) is that it is a compression system for outputting video to composite NTSC only. Supposedly a digitzed picture from DCTV can take as little as 33K of disk space (!?), and there are special paint programs that let you manipulate these special images. Hopefully we will get a peak at it when AmiExpo rolls through or something. If anyone has definite information on these new video enhancement products, please set the net.record straight. +---- Robert Huebner huebner@aerospace.aero.org The Aerospace Corporation +----
