The HP9000 we also had soured me from UNIX for good
H-PUKES and to some extent the hardware it ran on are some of the things from the old, real -
hp- I have the least affection for. Compared to Solaris it was directly unfriendly, and compared to AIX, it was simply not finished. The fourth of the large commercials, d|i|g|i|t|a|l UNIX, was much more a hacker's Unix, purer BSD and very competent. I never ran SunOS 4 and earlier, but I suppose it was similar. Thankfully, I had access to compilers and such for DU, and they made software scream with speed; nothing like the
gcc code.
Then, with the x86 BSD's, there was no going back. Oh, and Linux is for posers.
