I know this is a long shot but what the heck.
During a period of unemployment around 8-9 years ago (I think!), I borrowed a friend's Amiga 1200 (with tower and 4GB HD!). He had a copy of AMOS Professional and having never programmed anything before, I flicked through the manual and 3 months later I'd written a full-featured utility for guitar players which had a massive database of chord and scale fingerings, the ability to fully analyze chords you threw at it, a "suggest" feature which gave suggestions for "possible next chords" if you were writing a song, plus a practice feature with a metronome. It also worked out every possible fingering of a chord within a given fret range.
I don't mind telling you, I was as proud as hell of it considering it was the first program I'd ever written. Alas, a few years later I got evicted from my flat while I was living abroad and although my family were able to recover most of my stuff, I totally forgot about the Amiga under the bed and so I lost it all.
If anyone has some of the final cover CD's from Amiga Action magazine before it went out of print (or was it Amiga Active?), I would be grateful if they could take a look and see if a program called "FretKnot" is in the "reader submission" drawer. A cruder version of the program was on the last cover CD of Amiga Format too, but this was before I upgraded it to look better with 3D buttons and what not. I'm thinking about rewriting it today in Python, but I'd love to see my old version again!
Oh man, happy days! I spent many long nights messing around with co-ordinate graphics and plasma and the like. I think I even wrote a routine to convert a bitmap image into a bas-relief effect. Now how in the hell did I do that?
Well, I can but hope. It's great to see that there is still an AMOS community up and running. It's a great language and incredibly easy to learn, seeing as how I was able to write a complete program like that as a complete beginner having just read through a list of the syntax from A-Z.
