It's Raining Unices!

In pursuit of the execution of an assignment, I met and was introduced to:

Solaris (UltraSPARC) [actually, have met this during undergrad]
HP-UX (PA-RISC)
Tru64 (Alpha)
AIX (PowerPC)
Irix (MIPS-based SGI)

All of them are old. Lack decent shells (GNU bash), some lack decent editors (Emacs), all lack good GUIs, good browsers (Netscape 4 is everywhere!), decent compilers (GCC where present is 2.95 and ye gods, even 2.8!) etc.

Fun. Me thinks.
