I've finally figured out how to prevent my 3/60 on the third floor
from imparting a loud vibration to the rest of the house.  I put
it on an air mattress upside down (so the fan faces up), with the
shoebox rightside up on top.  The air mattress is one of those
ultra-light ones you put under your sleeping bag, and can be
obtained from camping stores.

(Disclaimer: I can't be responsible for your system if you follow
my advice; mine will probably be a smoking ruin when I get home
from work.)

Good Afternoon SAH-ers

I currently have a Sun-2/50 at home with a SCSI shoebox.
I has a 1 Meg motherboard and a 4 Meg expansion board with 
the SCSI controller.

I am looking into upgrading the existing machine to a Sun-3.
What are my options?  I have read on the net that the 2/50
could be upgraded to a 3/50 by just swapping in the 3/50 
motherboard.  I have also heard that a 3/160 motherboard can
be put in the 2/50 chassis.

I doubt that the memory expansion card would work, but what about
the SCSI controller?  Could the memory be disabled and the SCSI 
controller still work?

Has anyone performmed the above upgrades?  What problems did you run
into?

I am trying to make a decision withing the next couple weeks to see
if I should try to upgrade, or just go ahead and look into getting a
complete 3/50 system.  What is the going price on a 4-Meg 3/50?  8-Meg?

Email direct to me and I'll summarize, or just post back to the list.

Thanks for the help.
