UNIX has a very rich set of communications protocols and file sharing
software --Telnet, r-series, electronic mail, file transfer, and client and
server NFS. MachTen provides this full complement of protocols for the
Macintosh. With MachTen on your Macintosh, it is possible, for example, to
store all Macintosh applications on the hard disk of a remote UNIX
workstation and mount those applications on your Mac desktop with NFS. With
MachTen, you can even mount Apple Share volumes on your Macintosh and then
export those volumes using NFS.
MachTen has line printer spooling capabilities, so it can send printer
output to the printer of a remote UNIX workstation. Any Macintosh on your
LAN can send its printer output to a MachTen Macintosh, and MachTen can
subsequently spool that output to any printer in your UNIX environment.
Likewise, UNIX workstations can spool printer output to a MachTen Macintosh
and have that output printed on a Macintosh LaserWriter.
