DIGITAL AlphaStation 255 system

  Jag är nu glad innehavare av en Digital AlphaStation 255 4/233. Tack till Claes, Runar och Mats J! Och tack vare DECUS och Compaqs OpenVMS Hobbyist programmet kör jag OpenVMS v7.3 med C, Fortran, DecWindows/Motif m.m. Jag har också kontaktat Oracle för att se om de kan släppa till en licens för Oracle Rdb. Dessutom surfar jag på internet med Mozilla :) Inte ett öga är torrt!!!
