Hey thanks for those! Wow, there is one screenshot showing D7E1 actually running in there, so it is possible! :-O It looks like there's no Apple menu too, or at least no icon for it - weird.
Would you mind posting those if you have any that weren't in the link posted above? Would be interesting to see more of D7E1 - I know the 6100 should be ideal as they were surely running on similar machines at Apple at the time, it makes no sense to me why it won't work!
