Well take Wordpro 4+ for example. In a 32K machine, it had enough memory for a few pages of text. It would have been relatively minor software complexity even at 1MHz to use paged memory to obtain a much bigger text buffer. Ditto BASIC could be readily rigged up to use a paged memory architecture. Not everything needs a linear address space.
