This column in the LA Times has some history I did not know, and I have been familiar with Adobe and PostScript for a long time. Two lifetimes ago I even made sales calls at Xerox in El Segundo trying to help sell Texas Instruments microprocessors. Sometime after I worked for another company that had one of the first
Xerox laser printers. Not the 9700, but the Dover described down the page a bit. The office worked in was a few blocks from Xerox in El Segundo. I do not know how the bosses got hold of that machine as it was not being sold or marketed.
