Craig, to hear differently, please check out the rest of the thread. As
others have stated, the only modification necessary to have USB cards work
in the 3400 is to shave off 1/16 of an inch or so on the edge of the card
-not really an "upgrade."
Beverly, I read the rest of the thread; if it requires ANY modification AT
ALL, it is an upgrade, is it not?
When I bought a 20x CD-rom module, then put it into my 3400c's expansion bay
in place of the 12x CD-Rom, I am UPGRADING it from what it was before, right?
Even though it it required NO shaving....
Oh come on! When you insert something into the expansion bay, you're using a pre-existing capability. You've made no permanent change to the 3400 in question. (Or would you also say that attaching a mouse to the ADB port is upgrading?)
The point is that you can (as is shown repeatedly on this list about 5 or 6 times a year it seems, and can easily be found by searching the list archives) use a USB card in an *unmodified* 3400. You do, however, generally need to alter the end of the card in the prescribed manner to allow it to fit properly. As an aside, I've got a USB card that I use in my 3400 and I was able to use it without modifying the end. It *is* a tight fit, though, so I'd heartily recommend spending a few minutes with an XActo knife. The expensive CardBus modification only puts in a card cage that's got the proper keying for CardBus cards, and provides some electronic signal isolation between cards (if you've got two inserted). Note that this only comes into play on rare occasions when there are two high speed CardBus cards in. Given the number of folk that report successfully using FireWire cards, this ground plane portion of the mod is apparently unnecessary in most common circumstances. I suspect that most modern cards have better, lower power components and simply aren't as noisy. In short, this is like those sports records with the asterisks -- the 3400 is fully CardBus capable, with the asterisk that you need to alter the keying on the end of the card to ensure proper function.
Hopefully that puts this to bed for the next few months.
(And, to future readers that have found this message by searching the archives to find out about using USB cards in the 3400, thank you for using the archive search feature! You've now likely gotten your answer far quicker than by posting to the list and having the info dribble in over the course of a day or two...)
