buzzp,
Researching the evolution of the PC is very challenging. For instance: when you look up an article, from say, Paul Allen's bio, it contradicts what other articles say about him. Another example is Steve Jobs claiming to have invented the PC. It goes on and on like that. Frequently, these early PC illuminati had worked for a major mainframe computer company (IBM, Digital), and had "stolen" intellectual property.
The small company I had been at was a beehive of excitement at the time. It was located in an old house in Albuquerque. It went on to produce the "Altair" line of computers. When I was there, its signature product was a 14-digit or something LED display calculator - a rather large breadbox-size affair.
To change the subject as bit, when MicroSquish came out with its version of word processor, I remember a person opining that the Word Perfect word processor was far superior. Later on, same thing with Excel - some claimed that Lotus or Quattro Pro was superior. But the competing companies kept "one-upping" each other withe their latest version.
