The root of the AFS filetree is /afs. If you execute "ls /afs" you will see directories that correspond to AFS cells (see below). These cells may be local (on same LAN) or remote (eg halfway around the world).
### <a name="1.06 Which systems is AFS avail"></a> 1.06 Which systems is AFS available for?
-AFS runs on systems from: HP, Next, DEC, IBM, SUN, and SGI.
+AFS runs on systems from: HP, Compaq, IBM, SUN, SGI, Apple ([[MacOSX]]) and PCs with flavours of Unix.
+
+AFS has been available for Next and DEC (Ultrix).
Transarc customers have done ports to Crays, and the 3090, but all are based on some flavour of unix. Some customers have done work to make AFS data available to PCs and Macs, although they are using something similar to the AFS/NFS translator (a system that enables "NFS only" clients to NFS mount the AFS filetree /afs).
