I think of a personal computer as one that was owned by an individual for use in a home. The same computer could also be used in a commercial setting but these computers were often in homes. In 1979 I had about six HP 9825 calculators in my basement. These “calculators” were great computers but they cost many time more than my SWTPC 6800 system did. (I was setting up a contract project so these 9825 were just rented. There was over $100,000 worth of rented equipment in the house.) Even though I had a HP 9825 in my home I don’t think of it as a “personal computer”. ------------------------------- Michael Holley swtpc6800(a)attbi.com www.swtpc.com/mholley -------------------------------
