(Did you really write this Peter?) The CPU slot is not designed to remove the '030 from the system, therefore the motherboard still has to run at the speed it was designed to run at- just in case somebody does a multi- processor version of AmigaDOS, perhaps (I know, actually you should be using the '030 as an I/O processor). Also, what happens if someones decides they want to design a 50 MHz '030 or a 100 MHz ECL version of the 88110 to go into the board (not saying that such a thing will ever exist, of course :-)- should the motherboard be able to run at those speeds as well? Also, there are a couple of parts on the 16 MHz mb that are spec'd at 16 MHz- they won't run at 25 MHz to further differentiate the two mb's without making them too different. -- Skipper Smith | skipper@motaus.sps.mot.com Motorola Technical Training | 8945 Guilford Rd Ste 145 All opinions are my own, not my employers | Columbia, MD 21046
