( They do offer a board-changers-troubleshooting guide for $125 >>with no schematics or detailed technical information) About 13 years ago, I was a graduate student and would occasionally write articles for BYTE and some of the other computer mags. Since this was when personal computers (then called "home computers") were JUST getting started, there was a lack of I/O devices, particulary graphics devices. At that time, Fairchild introduced their "Channel F" video game which unlike previously available games had a cartridge which looked like an 8-track tape cartridge, but contained some type of electronics, which I assumed to be ROM, plus maybe some type of peripheral chip. ( I can't remember if the Atari system was out at that point or not). It occurred to me that if some type of plug-in interface could be made up using the cartridge slot, then any of the small computers of the day (I was using a SWTPCO 6800 system) could have a graphics output facility. If I could get something going, then I could write an article for one of the magainzes. Well, I called Fairchild, and it was obvious that they were not prepared for this type of request for technical information. After being shuffled from one department to the next, I was finally refered to a company, who had actually developed the system, which Fairchild was marketing. I contacted the original company, and was informed that since they were the "market leader" and had the "foremost position" in the video game industry that they were not prepared to release any technical information (especially to a mere graduate student, I inferred). I was gratified a short time later to see the "Channel F" system being sold for scrap parts by mail order surplus electronics places. - Bob Wier College of Engineering Flagstaff, Arizona Northern Arizona University ...arizona!naucse!rrw | BITNET: WIER@NAUVAX | *usual disclaimers*
