I had this posted a month or so ago and never got any feedback. It took over a  
month for me to get a check (they don't accept PO's) to Maxtor, but I finally  
got the board in last week, had our Tech Support people swap out the old board  
and put in the new one.  I did an fsck and I'm back in shape without anything  
(so far) missing. One thing I did learn during the month is that a cube with an  
OD (*and* 32 MB of RAM) is a usable machine.  I ran off the 2.0 Distribution  
OD, set up an account for my self, and ran a combination of local and  
NSF-mounted apps. I get 100+ pieces of mail a day, (locally) and run a number  
of apps (like NewsGrazer) off a central NFS server, but I found it quite a  
useful machine. Long Live the OD and the Cube!!
