Well, that’s about it. Looks like there was more to say than I expected; even if every bit offended someone different. Now, how can I get it to Scorpio News? My system supports nearly two hundred disk formats courtesy of Uniform, but I don’t even bother to look for Gemini … it won’t be there. And that’s a cue for another whinge. How come there are so many formats? Multiplying the disk sizes (4) by the possible sides (2) and densities (2) and numbers of tracks (2) gives a number not unadjacent to 32. What spirit of perversity causes every different manufacturer to select their own unique format? Pride, I suppose. If anyone knows whether the Gemini format matches any computer ever sold in America, I’d be most grateful for the information. For now I’ll send this in on an IBM 360k PC disk, which is as standard as a 3/16 UNF bolt. ●
