NOTE: I was tempted not to support Tetron when there was no response. But fortunately at the last minute some people sent some suggestions and opinions. Because of these cool/kind/great/fantastic/lovable/generous/etc. people, Tetron will continue to be supported. One problem though. When the A1200 and A4000 have a larger user base, I don't know what can be done for these people. AMOS does not work on these machines, and I am reluctant to rewrite the whole thing in C, as I have a lot of other projects to complete. But if there is enough interest, I suppose I will have to. At least then you will have 256 colours with nice backdrops. One of the reasons I took backdrops out was that I ran out of colours! At least now I know how to write a T*tr*s properly. Pity I learnt after I wrote Tetron :-) Peter Fregon '93
