Greg,
Re the IPX

You could shop around for Transcend memory. They produce modules for
SparcStations. For a SparcStation IPX(4/50) you can get 16Mb Modules
produced by Transcend. The OEM part number is X116Q. The Transcend part
number is TS16MSUNELC. Just check the sparc station numbers against your
box.

I know you are in the US but these guys sell a huge range of modules for
just about every computer ever made I think.

You can at least confirm that I have the details right and It might help
your search for something closer to home.

Or you can go to http://www.transcendusa.com the Transcend web site. There
is a list of partners which I guess are resellers. I didn't go into any more
detail that the main partner list.

Hope that helps
