Aha! Success....

Push harder you fool....

Having gone through my photographic memory (ha,ha) I realise I bought the Mac in 2003 and not in 2000. I now have therefore established that my machine is an aluminium 12inch version (for which I plead I have no boxes or data in this country and even the Apple website identified my machine as a Titanium DVI) which is supposed to used airport extreme, so I tried again and have managed, with much sweating about irreversible damage and bent fixings, to push home the afore-mentioned aerial jack...with the end result that....it all works! We are wireless on the internet!

Unfortunately the battery is so knackered that the machine needs to be permanently plugged in, which rather defeats the object, but hopefully we can organise a replacement battery at some later stage. The good thing is I can now run my Mac and my school computer from downstairs wirelessly, if you don't count power cables (even though there are only a couple of useful plug points in the house!). In a short time we should get a USB phone and then we can Skype till kingdom come.

Thanks for the encouraging shove in the right direction Steve. I was sweating. It still beats me how the Apple site got me in to the wrong frame of mind....
