I am trying this but still be limited. Still I am getting there I think.

This is the biggest factor that I have, I cannot justify the cost of a
new PC when I am not working and semi retired due to ill health. I was
considering putting SA on a 486 with 24mb of ram, have nothing else
running on the box so the box is given over to SA.
