not much. RH6.2 i believe wants at least a 486, but a 386 may work if you really need it to
, at least with a different boot image. you probably want a machine with a bootable CD-ROM so you don't have to create boot floppies. for memory, you probably want at least 64MB, but again, you could skim by with less. 1.2GB hard drive space is a good minimum, although i believe the full RH6.2 distro will install (barely) to an 800MB drive. so, essentially, for this older release, any pile of junk you have under the short leg of a table should work
(of course, then you'd need to find another way to keep that table stable
)
