While trying some benchmarks on my Mac II I noted that the results changed if I booted without MacsBug. After some thinking I traced the problem to floating point operations. Trying the Mandelbrot programs posted in spring gave me some figures for proof. Macsbug & Mandel881 5432 Mandel 881 without Macsbug 6653 Macsbug & MandelSane 1576 Mandelsane without Macsbug 2187 (I only tried the program for a minute or so per run, so these numbers may not be very accurate, but they clearly demonstrate the problem.) Maybe someone would be interested in finding out what MacsBug does to slow down the 68881... Juri Munkki mcvax!santra!jmunkki "Using Hypercard isn't programming, but it's almost as much fun..."
