Ditto, though a number of people commented that there was difference in the way the '010 and '020 expect the system stack to appear. > > One thing that'll be different is the way you do floating point. > Apparently on 68010's you have to do some fairly complicated things > to access the '881 and usually that stuff is in the run-time I think that starting with 3.5 there are environment variables to get the C compiler to put out '881 instructions instead of calls to floating point simulation software. However, I also think that there are some files (startup? libraries?) that turn out to be missing if one tries to pretend there is an '881. > It would be loverly to have an 020 in there tho'. I would love that, as well. By the way, I was (long ago and far away) once able to actually get a price for part number 105160253 ("Math. Acc. Unit MC 68881") that's listed in my "AT&T UNIX PC Service and Parts Ordering Information" - $2,520.00 list. Thanks, but no thanks. (I also believe that they decided not to market it - hmmm, wonder why it didn't sell? After all, doesn't everyone want to spend $2500 for faster floating point?) -- Steve Wampler {....!arizona!naucse!sbw}
