Over the past couple of years Kulbinder Kalirai has updated SEESAT4 to SEESAT5 including many performance and user interface improvements, now Dale Sheetz has taken it to Unix. The user interface is not for the faint hearted, but it is fast and reliable. Seesat5 is available as a Debian Linux package and as a Source Package from: /-binary/misc/seesat5_xxx.deb ftp://ftp.debian.org/pub/debian/buzz/- \-source/misc/seesat5-xx.tar.gz or: ftp://dwarf.polaris.net/debian/seesat5_0.90-3_i386.deb and seesat5-0.90-3.tar.gz (10am-2pm, 7pm-10pm, EDT weekdays) Debian Linux is free and available via ftp from ftp.debian.org and it's mirrors.
