I guess I was not clear enough: no, AFAIK, nobody has
written/built/manufactured/fabricated/engineered anything that could
resemble or be more or less closely related to an USB and/or FireWire
adapter/card/driver/whatever. If you're sticking a USB or FireWire PCMCIA
card in your Newton, and if the Newton doesn't have any driver that claims
to recognize that card, the card won't be used and power will be cut off.
Now, suppose that there was a driver, I highly doubt that the PCMCIA
circuitry in the Newton would be able to provide enough power to recharge
any external device. However, I'm not a hardware engineer, so I could very
well be wrong, and would love to!
I'm still waiting to hear from any Newton owner that they're successfully
using a USB or FireWire card in their Newton, but I confess I won't hold my
breath...
