No Doubt about it, you need a Kaypro.
They came with just about all the software you would need to run a small
office, Wordstar, DataStar, DB2, Basic and the list went on.
They were very reliable. I used mine right up until 1991. The Kaypro 2X I
had bought in 1984 ran WordStar faster than the IBM Xt's.
As they were the portables of the day, it will take up less space than some
of the other CP/M machines of the time period.
My two cents.
