Wow, was not my intention to create such a stir, just expressing my opinion.  I've tried linux in the past and was not very impressed.  Sorry if it offends anyone.  I don't profess to know all the in's and out's as I don't do this for a living, I'm only a hobbyist.  I do have experience on many unix flavors and found IRIX to be about the easiest to work with, at least for me.  I started out with an old DEC PDP running 6th Edition, migrated to a VAX and MicroVAX, then the DECstation and VAXstations, all running Ultrix, but I did play around with RSTS/E and RSX a bit on the PDP's.  Experimented a little with NetBSD on the DEC hardware, then migrated to the SGI's and IRIX.  Currently have six systems in the collection along with two SUN SparcStation 5's running Solaris 8 at the moment.  Pic's available upon request  
 
  On a side note, I have two IBM systems available that I will probably never use and would like to get out of the basement due to space considerations.  They are and IBM System/36 Baby and an AS/400 Advanced 9402/3xx.  Both work fine, no problems, just don't have the time to do anything with them.  The System/36 I have all the original documentation, manuals, and software for, the AS/400 has only what's on the disks.  If anyone's interested, drop me a line by email.  I'd hate for these to end up in a dumpster.
