The mc68030 (25 Mhz) costs over $200, and the mc68ec030 (25 Mhz) costs less than $70. I think that both of these prices were for 100 pieces or so. My recollection is that I could get a single 030 for about $250, and one ec030 for $70. (um, yes, about the same as the 100 piece price.) The ec030 comes in an inexpensive plastic pin grid array package. That explains a good deal of the price difference. Apple is using plastic packaged 030's (in SE/30's at least), but I haven't been able to get them, myself. The 40 Mhz ec040 is out, or nearly so. I didn't get a price for it, but it might be something to look into. -- steve.ligett@dartmouth.edu or ...!dartvax!steve.ligett
