A straight gender changer will NOT work. The Amiga 1000 provides +5V, NC, and RESET on pins 23, 24, and 25 respectively. The Amiga 2000 provides these signals on pins 14, 15, and 16 respectively. Therefore you are not supplying plus five volts to the DigiView device. If your VCR has a rock-solid freeze frame, you can do B&W digitizing (16 shades of gray). To do color, you have to have the camera and color filter. That's because DigiView digitizes RGB as 3 monochrome exposures. A VCR cannot provide red-only, green-only, or blue-only signals. -- +----------------------------------------------------------------------------+ | TYMNET:JMS@F29 CA:"POPJ P," UUCP:{ames|pyramid}oliveb!tymix!antares!jms | | INTERNET: (Office-1.ARPA is no more) PHONE:Joe Smith @ (408)922-6220 | +----------------------------------------------------------------------------+

(Still 3 passes, a switch on the box for Digiview owners.) It was made for Perfect Vision, seems to work for Digiview, although the docs mention that it may not get along with some VCRs. (I like it... We're using it with Digiview and a NEC VCR with digital freeze.) One thing I'd like - a hack to make the color splitter think it's a Digi-Droid, controllable through Digiview's software. (Through a DB9 on the back of the color splitter box, the Perfect Vision digitizer is tied in; the software can then control the RGB passes automatically.) Since the Digi-Droid does the same sort of control (um, maybe?) to a camera's color wheel, could it be made to interface with the color splitter's controls? [This technical discombobulation on only one cup of coffee; sorry. ;^)] Disclaimer - I own Digiview and the color splitter - otherwise unconnected.

You can however get the "color splitter" from sunrize technologies, about $89 I think. I have one, it has a 3 way toggle switch on it for Red, Green and Blue. Plug your vcr into the color splitter via an rca cable, plug the color splitter into the digiview and use the red, green, blue menu items of digiview and move the splitter's switch. It does work. Mine was one of the first ones I think, no manual in the box, nothing but the colorsplitter with a bunch of connectors on the back, so it was a guess what they were for. ------------------------------------------------------------------------ "Those whom the gods would destroy, they first make mad" He who steals my core-dump, steals trash
