Don't bet on it, you would lose. If you read Dave Haynie's posts (mostly in .tech, I think) you would find that, among other things, the FAST memory on the motherboard can be accessed faster by a master in the coprocessor slot than by the 25MHz 68030 on the motherboard! The 68030 is a very nice machine as sold, but it was designed with an upgrade path in mind just as the 2000 was. The 2000 was designed with a syncronous 68020 board in mind, the 2620, but Dave Haynie (and GVP) only had to do a little magic to put 25 (and 33 and 50 and 60) MHz asynchronous processor boards in the same slot. The 3000 is designed to support both asynch and synchronous boards in its COprocessor slot. I'll be in my office for only a day here and there in the few weeks so send any interesting comments via email (and flames to /dev/null). -- Robert I.
