Target Praxis in Unix based Systems

~1985 - now

My friends were working in the computer industry very early, this made it possible for me to see many different Operating Systems on different platforms. Trying to compile and install free Unix sources from comp.sources.unix was a nice adventure in former times. Imake  and autoconf makes compiling and installing Unix sources in nowadays relatively easy compared to the work involved in that time, where sources were not always good prepared to compile fine on different target platforms. In that days I started with "tools" like rogue, hack, less, elm and soon started to use UUCP and so bnews, cnews, rn...
Everything started on a original IBM PC (80286, 512K RAM, 20 MB Harddisk, 10MB DOS, 10MB Xenix)
8086 Microsoft Xenix I saw as well, yeah, Microsoft tried to use/push Unix in these days ;-)
PCS Cadmus (a friend of mine had this awful machine which heats 20qm in the winter with no problems)
SCO Xenix 80286 (was first able to compile rogue successfully)
SCO Unix, SYSV 80386 (my first System with 8 MB RAM and Co-Processor)
Interactive, Everex SYSV R3
Everex and Intel SVR4 (yeah, I saw this release with certain compiled in SCSI Disks)
Linux Slackware 1.0-3.0
Linux SuSE, tried some release
Linux RedHat, Gentoo
FreeBSD 1.0-5.x, -current
SunOS 4.x, Sun Solaris 2.0 – 2.6, 7, 8
