Lines: 24 In principle it is possible to put a 68010 in one of the 14 Mhz boards, but no one (to my knowledge at least) makes a 14 Mhz 68010. The folks at CMI said that one might be able to find a 12 Mhz 68010 that would run at 14 Mhz, by trying out a few of them, but an 8Mhz (the cheap ones) would have little chance of working. I had an 8 Mhz 68010 in my A1000 which I tried in my CMI board and it didn't run. The CMI board is somewhat faster than the 68010 however. I feel that for the sort of stuff I normally do, I got about a 10% speedup from a 68000 using the 68010 and about that much more using the CMI over the 68010. I also dropped the bux for a 68881 but I still don't have the 1.3 IEEE librarys that are required to use the FPU. The CMI board uses the 68881 as a peripheral device( this is supported under 1.3...) but you can't just compile stuff under the MANX 68881 option and get it to run because MANX assumes the 68881 is actually hung on the bus along with a 68020. This latter method of using the 68881 is faster, but somewhat more expensive... steve collins (at least that's how I heard it....) When you're as dumb as me, you never even feel the flames...
