Good memory. Nice to see that Commodore is reading the latest errata on the '040. This should say something ;-). MOVE16 is a nice thing to have when you _need_ to move things around very quickly. >Perhaps you mean FP that uses inline for instruction that are in the CPU, >and calls subroutines directly for things that are emulated. >That's all I can think of. Software FPU function emulation is not a problem. You don't need something like MOVE16 or any 040 specialized instructions to do it. On that note, I was hearing that 2.04 now has '040 cache control support - is this the case? Or am I still going to have to SetFunction() to get the PFlush() commands in there? I suppose that I could call, but I've already got your attention, and this is cheaper ;-). >Also, on what released '040 board would they test it? ^^^^^^^^ If it was released, then I wouldn't be whining about it. This must be a trick question, right? ;-) I'm sure if they were responsive, then _someone_ may lend them a board to test it. > I take it 5.10a has a bug that's affecting you?

It has something that I haven't taken the time to track down.
