[NON-CP/M home computers]

What IS a "home" computer?

I say that an unexpanded TRS80 is a home computer.  EXPANDED, it can have 
other uses.  If you take total number sold, MINUS sales of the expansion 
interface, then you will have the number.

Although it was not Z80, the original ads for the Lisa showed it on the 
living room floor with a toddler playing with it.  THAT wouldn't justify 
its price range.  Even the 5150 had a couple of ads like that.  Without 
disk drives, is it anything other than a home computer?

I think that there were more, but not my corner of the field.

What about MSX?
Not in USA, but Z80, and not CP/M, although the OS might have had 
similarities.   Was it a "home" computer?

You will want to classify Northstar as "business" not home, but 
NSDOS was not CP/M.
