I have 7 ethernet, 2 serial, CF, IDE and USB on the device dying. I have 1 ethernet, 1 modem, 2 USB, 2 PCMCIA, parallel port on my other 7.0 system (OLD Toshiba Laptop). I'm also a little limited by supplies. I'm 9 miles off paved road on the edge of the Atlantic Ocean. Supplies aren't scheduled to be brought in to me until the 12th. Its an 11 mile walk to my car. Great view though. :-/ Tuc
