     Frazer Owen and James Robnett produced much of that document
except the AIPS file changes.

       The web pages says to re-run INSTEP2 and INSTEP4.  So far as we

and IMAGR and TVBOX verb in AIPS were among the known failures.

I did not do anything to SPFLG in quite a while other than have it
display multiple IFs at once.  These new computers have the memory and
speed to do things well that older Solaris boxes choked on.
