I remember using Wordstar 3.0 on a Xerox 820-II CP/M-80 system. It was considered a business system, but became available at the Xerox Surplus Store in I think the Dallas area by mail order, back in the latter 1980's. All surplus, used equipment and software. Ran in 64 KB of memory on 180 KB single sector disks, Z-80A processor at a whopping 4 MHz clock speed handled the Intel 8080 code that most software was encoded in. I bought stuff to use at home there, because of the clearance prices. When new, systems were a couple thousand dollars.
Later upgraded disks to double sided double density 360 KB. Had both 8" floppy drives and 5.25" floppy drives. Required installing a special interface card for DSDD. Later, upgraded to 16/8 with 80186 coprocessor board inside the expansion chassis to run 3 OS's, CP/M 86, CP/M 80, and generic MS DOS 2.0. Installed a 5.25" MFM 10 MB hard disk, but had to modify the 820-II's BIOS in 16/8 mode. Xerox was hard coded for 360 cylinders and 4 heads. Used Miniscribe I acquired was 720 cylinders and 2 heads. Also patched the partition and formatting software to take into account the differences, but got it all to work.
Anyway, probably too much information for most.
Came with a separate spell checker called Spell Star. Things have changed quite a bit since then. But, I observe, although we seem to be so called technology smart, overall, we seem to accomplish about the same amount of work with manual methods back then as we do now with all the tech. Don't think we are really any further along than before. Really.
