I realize that this has probably been asked before, and if so I apologize, but I still need some help, ok? :-) I need to be able to convert analog RGB (from an Amiga computer) to be displayed through the superVHS connector on a TV. Is there any cable/box/gizmo available to do this? Has anyone built such an animal and can send me the plans? Please send email and I will summarize, rather than take up valuable space here.

Ok, for all those who asked for it :-) Here is the summary of the responses that I received on how to convert RGB to SuperVHS. I was hoping to get plans on how to make a cheap converter, or something, but alas, no such luck. Most people told me that I need an expensive converter ( $500 >) Well then, without further ado: ----- Date: Thu, 27 Apr 89 07:26:45 MDT From: Don Middleton <don@bierstadt.UCAR.edu> Subject: Re: RGB ---> SuperVHS Newsgroups: rec.video,comp.graphics In-Reply-To: <567@corpane.UUCP> Organization: Scientific Computing Division/NCAR, Boulder CO Cc: I have a little box that transcodes between the various NTSC composite, component, and SVHS signal formats. I believe it is made by TrueVision and, while I haven't tried it yet, I've had a couple of people tell me it does a fairly good job for the $600 or so that is costs. *----------------------------------------------------------------* * Don Middleton * * National Center for Atmospheric Research * * Scientific Visualizaton Group * * PO Box 3000 * * Boulder, Co. 80307-3000 * * don@ncar.ucar.edu * *----------------------------------------------------------------* ---------------------------------------------------------------------------- From: Hubey <hubey@pilot.njin.net> Message-Id: <8904270559.AA09351@pilot.njin.net> To: sparks@corpane.uucp Subject: Re: RGB ---> SuperVHS In-Reply-To: USENET article <567@corpane.UUCP> There is a commercial "thinggy box" you can buy for about $50.00. Since the A2000 and the A500 don't have composite color output, there are electronic boxes out there (at least two that I can remember) which will take the RGB output of the Amiga and output a composite signal. At least one of these boxes also outputs the Super VHS type S and V(?) signals. regards mark [ editors :-) note: Now this sounds promising. Any one know what box this is?] [ not the composite only box, but the one with SVHS out? JSparks] H.M.

I have before me a 1-page glossy brochure describing VIDtech's ScanLock Model VSL-1. It claims broadcast-quality genlock of the Amiga to a reference (NTSC, PAL, or S-VHS video) and keys (superimposes) the Amiga video over the reference video. The Scanlock transfoms the Amiga RGB video into NTSC, PAL or S-VHS (Y/C) format output. It is equipped with independent FADE controls for reference and computer video. It can be powered by the Amiga or externally. Front Panel Stuff: Power Selector/Bypass Switch (amiga/off/external) w/led Reference video input selector (NTSC/S-VHS) w/led Reference video output selector w/led Amiga Video Output Selector w/led Keyed video output selector w/led Fade function selector w/led Reference Fade Controller (slide control) Amiga Video Fade Controller (slide control) Normal/Reverse Key Video Selector w/led Normal Video Reference Indicator w/led They look like membrane keyboard switches on a light grey panel. Back Panel Stuff: (power cord and fuse) RGB Out DB-23 connector RGB Load switch (HI/75ohm) Key Out (BNC connector) Remote (14 pin DIN connector) Reference Inputs: NTSC In (BNC) Load Switch (HI-75ohm) NTSC LOOP (BNC) S-VIDEO IN (S-VHS jack) S-VIDEO Load Switch (HI-75ohm) S-VIDEO LOOP (S-VHS jack) Video Outputs: NTSC (2 ea. BNC connectors) S-VIDEO (2 ea.

I picked up the brochure at Amazing Computers in Dallas, but they did not have any in stock yet. (delivery date unknown) (price unknown, assuming > $600.) Looks like it does everything for the high-end pro video and low-end broadcast market, proper connectors, etc. but have not seen the quality yet. Let me know if you find one somewhere, and what you think of it! Standard Disclaimer: I never heard of those guys before. Just looking for that functionality myself. [Imagine...being able to play F-18, OutRun, and Mean 18 on my new 35" Mitsubishi TV via S-VHS Y/C inputs! Yeah! oh, well...maybe Christmas 1992. See Ya!

Cc: CMI (Creative Microsystems) makes a box called the VI Video Interface. It converts the Analog RGB signal to composite, separate chroma-luma, and depending on the model, RF. I beleive that you can wire a cable to go from the separate vidio to the SuperVHS connector. The picture quality out of the box is very good from what I've seen. I believe that it comes in models with or without the RF, with the more expensive RF version retailing for $99 (the other is less). It comes in an external model and internal for the 2000 series.
