The Unix Hardware Buyer HOWTO

Eric Raymond


Revision History
Revision 3.02004-02-21Revised by: esr
Power-protection stuff moved to UPS HOWTO. DIMM memory is gone. Tape drive don't make sense any more. Lots of the theory from my "Ultimate Linux Box" articles now lives here.
Revision 2.42003-02-22Revised by: esr
URL fixes.
Revision 2.32002-08-06Revised by: esr
Buying at the low end isn't a lose anymore. I recommend Athlons. Nuked the section on video standards, EDID takes care of all that now. Also removed the section on older memory types. And keyboards, as the "ergonomic" ones all vanished along with the 1990s carpal-tunnel scare.
Revision 2.22002-08-05Revised by: esr
New section on DVD drives.
Revision 2.12002-07-08Revised by: esr
Corrected Kingston URL. Various small updates for the last year. This HOWTO is much more stable than it used to be.
Revision 2.02001-08-09Revised by: esr
Major update. Revisions based on Ultimate Linux Box experience. Caches are on-chip now. DDS4 tape drives are here. 486 machines, CD caddies, and most non-DDS backup technologies are gone.
Revision 1.12001-06-13Revised by: esr
Mid-2001 update.
Revision 1.02001-02-06Revised by: esr
Initial revision; but see the history in the introduction.
