I remember once upon a time seeing (in BYTE I think) a picture of the insides of the 1040. There was even a nice space where the RF modulator was meant to be. Perhaps we could add our own? Please correct me if I'm wrong and inform me if I'm right. Thanks.

[] Last time I looked inside my 1040STf it still had an empty space (next to the video jack) that was obviously designed for the modulator Atari still owes us. (That BYTE preview said it will be there, and so does the nicely printed manual that came with my ST...) That space has some traces for an emitter follower or something, but not for the main part of the modulator. But forget about the modulator: how about getting just plain composite video (no RF) out of the 1040? Anyone knows how? Or is this what was meant in the posting, modulation meaning in this case the encoding of the colors in the subcarrier? - Moshe Braner

**********[Ignore header path]********* I just received the latest issue of Current Notes newsletter and they had an interview with Black Patch Systems (the mail order company everyone loves to hate). He stated that by now they would be selling a black box that would allow you to interface a 520 or 1040ST to any IBM-type RGB monitor. It will sell for $39.95. I know this doesn't help if all you have is a composite video monitor but it might be a nice answer for several who bought the monochrome system and want to be able to enjoy color and have the proper monitor available.

Since my posting yesterday, I remembered another article I read on this subject. The July (I think) issue of Computer Shopper had an article that mentioned a company called At Your Service run by Mike Spires. He says he has the video connectors for those that want to make their own cables and he sells for $20 a 5 foot cable with composite video and audio out. For those with a 520ST with the built-in modulator, he passed along an undocumented feature. You already have composite video on pin 2 of the video connector. If you would like to contact him for further information his address is: At Your Service 2856 Leechburg Rd. Lower Burrell, PA 15068 (412)-335-4477 He is also associated with an ST FOREM BBS called the Atari Elite BBS. He receives messages there also. The number is (412)-384-5609. They run at 300, 1200 & 2400 Baud. Kit Kimes AT&T--Information Systems Labs 1100 E. Warrenville Rd. Naperville, IL 60566 ...ihnp4!iwvae!kimes

Note to 1040 users: just having this cable won't make your ST into a composite-capable machine (this is the impression I was under when I bought the cable -- guess the ol' brain cells are decaying faster than usual). What we need is someone to design a box, or for Atari to sell a box, that will fit onto our video output and give us composite). I have seen a 520 with monochrome monitor and composite color. The color is not as good as the RGB, but it will do for games. I was almost tempted to trade my 1040 for the 520, but the extra 512K memory and built-in drive (plus the hope of composite sometime, somehow) was enough to keep me in the 1040 camp.

I built a little board that would generate composite video
output from the RGB that the ST provides, using an MC1377 and very little
other components. The board is still lying around (I don't have a colour
monitor, and the board was originally designed for someone else) and I
have the schematics I used. If people are interested, send me a SASE and
I'll mail you photocopies of the schematics. If you are handy with a soldering
iron, the construction should be quite straight-forward.
