V2.9 is a limited release. If you do not find a binary distribution for the system you are interested in, and to which IRAF is already ported, that means that we have not installed V2.9 yet on the system in question. Further upgrades are always possible. In addition, new ports are always in progress. Contact the IRAF group (iraf@noao.edu) for information on the availability of IRAF for host systems other than those found in this archive. Other systems to which IRAF has been ported: Alliant Convex VAX - BSD 4.3 VAX - Ultrix In addition, Macintosh A/UX, IBM AIX, and SGI ports are planned at this time.
