I was just wondering...I'm planning on buying a Personal Workstation 500, and i've seen claims on the net that PWS can go up to 667Mhz (the limit of 21164 right?), so in theory, could i just drop in a 667Mhz chip and replace the 500? And just out of curiosity, lets say the PWS's cpu goes bad, could i replace it with the 500Mhz cpu that was in my DS3305? How interchangeable are alpha cpus? Richard Fillion rick@rhix.ods.org
