Around the mid 90's I bought the Dice C compiler for the Amiga. I think it came with a book(?) I was really happy with the price. It was on a special markdown price. I counted it as one of the best purchases I ever made. I was doing a PhD in Applied Mathematics at the time, nearly all in Fortran. But I was interested in C. It turned out that me learning C was a great decision as it led to me being a professional programmer.

I think the Amiga collapse not too long after I bought the compiler. Maybe the declining sales of the Amiga is what the authors decide to sell the compiler relatively cheaply. Matt Dillon wrote the compiler, and subsequently went on to create DragonFly BSD.
