Easy. If you had one and but not the other. But now, it's so fricking
cheap anyways...

Remember who was making this: The IBM employees that wanted to be like
Apple. A bunch of rogues with a mission.... but not to much in the way of
$$$.

I figured. Most of the chips I've seen from that era in the x86 arena are
AMD or someone, but Intel less often than you'd think. (Or, perhaps, if you
know what I'm talking about, just as often as you'd think.)

Hmm... see, that just isn't an economical idea. It might make more sense
to write a utility that figured it out, or to do something of that nature,
hand them the floppy (or tape, etc.) then say 'check.' But anyway, I'm
sure it was pretty good on cusomer satisfaction. Besides, having a spare
can't hurt.
