I tied DEV SEL L for my homebrew LPT to +5 and now F4 runs. I am curious if the EAE is used with F4. The Language Manual says it is, but it is only mentioned in one place. There is nothing else to select using it or not using it. I looked at the sources for various parts of F4 and can't see that any of the EAE instructions are used in it although I also don't know that I have source for the floating point library itself.
