If you're working with old beige hardware, keep in mind that some older beige and newer USB cards have a tendency to not always be compatible. Our luck in shop has probably been 2 in 5 work, 3 in 5 just lock up in OS 9 and earlier, with the card installed. (thats with multiple different cards, btw)

So bear that in mind when you order, and keep the receipt if it doesnt work! smile
