We sold the Xerox 8010 STAR Dandelion to corporations and specialty businesses looking for the flexibility of graphics and typefaces in 1981. See the photographs at:
Xerox 8010 STAR (Dandelion)
In the early 1980s, I worked for a company that had the first two Amdahls that rolled off the assembly line (mainframes). But I did corporate forecasting on my Apple, using Visicalc. The code for for mainframe took an overnight run, with more than 5 minutes compute time (at $200 per minute). On the Apple, it ran for free. Either way took the same amount of my time. Should have billed the company $200 per minute, but that was job security.
