The Sinclair ZX80 (predecessor of the Spectrum) was Z80 based. I know, because it was my very first computer.
Not really ideal for word processing and somewhat limited with 1KB (yes as in one kilobyte) of RAM.
You could get a rather expensive 16KB memory extension. Alas ,this had the problem of disconecting every 30 minutes or so, due to thermal issues. So you had to be really sure to save your work to datasette (don't ask!) in very regular intervals.
Fun times!
