The mouse required a mouse pad with the grid on it, and the entire ystem came with a spreadsheet (VisiOn Calc) plus wordprocessor and database. I think what killed VisiOn was that fact that software development had to be done on a Vax minicomputer as the XTs didn't have the capacity. A little bit of ancient history for the young 'uns....
