hello! i just bought a used Ibook g3 800mhz, and i does not come with the airport card, i was searching on ebay and came across this: http://cgi.ebay.com/Apple-Airport-Co...QQcmdZViewItem what you think of that? would it work as good as a original appel card? will ti damage my computer? or should i get an original apple card? i got this email from them; Yes, I can gurantee it will not damage your Mac. My card and the apple airport card are both 16-bit PCMCIA cards and follow the standards of PCMCIA. Moreover, the airport slot conforms to the standards set forth for a PCMCIA receptacle slot. I have DOA protections for buyers stated in my listing. I do not have a warrantly because I have never sold a bad card or had a reported failure. Warranties are based on failure rates, I have no failures to speak of. I have some customers from 2 years ago reporting the cards still work great. thanks for your help!
