 !!! What's the absolute minimum requirement for wireless access on a Mac? 
+An older laptop and a cheap PCMCIA card.  Ebooks and Newtons also have PCMCIA WiFi drivers available. 
+The minumum I've ever heard of being successful as a '''client''' node is a (http://www.lowendmac.com/pb/540.shtml Powerbook 540), System 7.5.3, an Orinoco or co-branded PCMCIA card, and the Orinoco drivers. 
+Note this 1994 laptop isn't even a PowerPC (33 mHz 68LC040 CPU), usually has dead batteries and not enough RAM, and is excruciatingly slow.  PCMCIA slots were optional.  The (http://www.lowendmac.com/pb/190.shtml 190 series) is of the same era, and had slots as standard. 
+A more realistic minimum is the (http://www.lowendmac.com/pb2/5300.shtml Powerbook 5300), a 100 mHz PPC machine with slots as standard, and still available for next to nothing.  It will also run versions of the MacOS up to 9.1, compared to the '040 machines which are stuck with 8.1 or lower. 
+Any of the more recent (http://www.lowendmac.com/powerbooks.html Powerbooks or iBooks) should be fine. 
+With Ethernet or Localtalk (printer cable) networking and the right software, these machines can act as bridges to the rest of your fixed network. 
+So to summarise: 
 '''Host Machine:''' 
 One of: 
-* Laptop with a PCMCIA slot or an Airport slot. 
+* Laptop with a PCMCIA, Cardbus or internal Airport slot. 
 * Desktop with PCI slots, an Airport slot. 
+** Note many PCI and PCI Cradle solutions are not supported with G3 machines.  See [Apple] page. 
 * Any machine with USB or Ethernet using an external wireless adapter/AP.%%% 
 '''Supported wireless adapter or AP''' 
-One of:   ''(Note:  Must have Mac driver software available)'' 
-* PCMCIA/Cardbus card 
+''(Note:  Must have Mac driver software available, although some rebranded cards can use drivers from their chipset cohorts, with occasional hackage)'' 
+One of: 
+* PCMCIA, Cardbus or Airport card 
 * PCI card 
 * PCI cradle with PCMCIA/Carbus card 
-* USB wireless adapter 
+** See note above about G3 issues 
+* USB wireless adapter or Ethernet to wireless bridge 
 * Free-standing base station, AP or router 
 
-'''Software/OS:''' 
-Officially, MacOS 8.6 is the minimum for the Airport drivers.  This means a PPC machine, as 8.1 was the last release to run on 68k hardware. 
+'''Operating System and Drivers:''' 
+Officially, MacOS 8.6 is the minimum for the Airport drivers.  This means a PPC machine, as 8.1 was the last release to run on 68k hardware.  There are Orinoco drivers available for System 7.5.3. 
+For a '''routing''' node, you're probably looking at some (http://www.eskimo.com/%7Epristine/unix.html Unix) flavour or (http://web.espy.org/apple-flavored-unix/ other), or MacOS X.  The minimum machine I've heard of there is the 6360/Debian/Ricoh cradle/Orinoco Silver card system that (http://zog.net.au Zog) put together. 
 
-I have heard of people running the Lucent Orinoco drivers under 7.x, on 68k machines such as a Powerbook 540; more info when available. 
+OS X capable G3 machines can be had on eBay for around $120-$150 desktop or twice that for a Powerbook or iBook.  These machines also have the great advantage of using standard PC RAM and IDE/ATA hard drives, although some of the older machines like the 6360 can also use IDE drives. 
 
-Airport cards, and the guts of the Airport base station, are made by Lucent/Agere for Apple, and are internally identical to their Orinoco Silver cards.  Note that you cannot use an Airport card in a PCMCIA slot, nor vice versa, because the slots are physically different.  Airport drivers are "supposed" to recognise Lucent Orinoco cards and their re-branded clones (Enterasys, Cabletron), and vice versa, but one member has reported a failure to recognise. 
+'''Airport vs PCMCIA slots''' 
+Airport cards, and the card in the Airport base station, are made by Lucent/Agere for Apple, and are internally identical to their Orinoco Silver cards. 
+Note however that you cannot use an Airport card in a PCMCIA slot, nor vice versa, because the slots are physically different.  Airport drivers are ''supposed'' to recognise Lucent Orinoco cards and their re-branded clones (Enterasys, Cabletron), and vice versa, but one member has reported a failure to recognise. 
 
 '''Comments:''' 
 [RyanM]  I've installed an Avaya card into a 17" imac, worked perfectly, apart from it being a struggle to plug the external antenna socket. 
 OS X.2 recognised it as an airport card, and upgraded the firmware automatically.  It also works in a Powermac G4.
