The Cardbus cards has a gold plated strip on the connector. As seen in the pic about half way down the linked page. The PCCard did not. hamilton

If you google for "Wifi Module" you will see that there are a number of alternatives, not only interfacing through a serial port but also through an SPI interface. Andrew

Personal experience rocks! You wouldn't happen to know off-hand, Andrew, which edition of Bentham the Wifi article of interest may have appeared in, would you? I can't seem to find it in my very tatty old 2nd edition. Yes, I'm stepping into the 'making a fool of myself' domain by naively proposing the re-use of an otherwise junk wifi card. The $1 throw-away Ethernet card solution to embedded TCP/IP went over really well with 8051 crowd, so I figure it's worth looking the twit if I can provide an equal number of enthusiasts, with as highly affordable a weekend's entertainment.

I have the same edition of the book as you but, at about the same time, I also bought one of the chipweb wireless kits from Jeremy's company (<http://www.iosoft.co.uk>). Looking at the website it is all still available. When I have contacted Jeremy in the past he was very helpful. > Yes, I'm stepping into the 'making a fool of myself' domain by naively > proposing the re-use of an otherwise junk wifi card.

There are, almost certainly, a lot of those cards around. Using them for 8051 networking is definitely better than them contributing to landfill! Andrew

Yes, I stumbled upon the http://iosoft.co.uk site shortly after inquiring to you about my TCP/IP Lean edition confusion. I found the ER21 embedded 802.11b development kit for the PicMicro, and which incorporates a PCMCIA Wifi module. Jeremy certainly seems to be the man to consult in this area, yet I was hoping for a less valuable solution to his apparently very professional software and hardware offerings. Well it doesn't look like there is much, if anything, available within the realm of uController to PCI card interconnection. Conceivably this may mean that my line of inquiry was indeed stupid, and that there is considerably more to the problem than the ISA interface presented. Looks like I'll have to do a bit of PCI bus research, as I'm not prepared to chuck it in just yet. Thanks again everyone for your links, comments and contributions. They are all very much appreciated. Modafinil.
