From the picutures I have seen there does not appear to be >more than one external floppy slot, so can you have more than one floppy? >Or is that second floppy actually internal with no external access :) He didn't even mention the slots :^) and in the pictures you saw, I assume there was a striped peice of plastic next to the 3.5"floppy. You take this peice off when you put a second floppy in the system. (You can have 2 hard drives and 1 floppy or vice versa.) Now for a couple of questions: I want stats! We ran a demo called KLIDEX simultaneously on a 2500/30 and a 3000 at the local dealer, and I guesstimate the 3000 was about 5-10% faster. (Klidex is a damn fast line and curve pattern drawer.) We were going to try out a Dhrystone Benchmark on it but we forgot to bring it and I don't think it would be fair without an A3000 specific compiler. ANYWAYS, can someone give us a hint as to how fast it is compared to a 1000? a 2500/30? etc. I want to see this beast's number crunching power! (BTW, any rumors about an '040 card? which brings me to my next question...) From looking at the pictures in the magazines, It appears that on the right hand side of the system there is the case on top, the drives, some sheilding/ support, and then the motherboard (from top to bottom) Well, the 200 pin cpu slot looks like it is crunched right under the floppys. Is there space under there for a card? I can see something like this: |----------------------------------------------------------- | |------------------------| | | | <-- drive | |------------------------| | -------------------------------------------------------- | |------------------------------ <--expansion card | ^ <-- connector | |-------------------------------- <-- motherboard |------------------------------------------------------------ Is that what will happen? It looks tight! If not, where will the board go? -jason nyberg >-- >Alan Bair >SPS CAD Logic Simulation & Test >Motorola, Inc.
