The first end user sale was to a chicken farmer in the South who programmed the Datapoint 2200 to write payroll checks. You could say a chicken farmer was the first user of a programmable personal computer.
The Datapoint 2200 in our Museum is a Datapoint 2200 version II and Jack just furnished more information about the version II - Here are his comments.
"Also the instruction set for the 8080 was also a Datapoint II (less two instructions). So not only was the 8008 a Datapoint computer so was the 8080. The story is in the chapter about Datapoint and Intel. The Datapoint II was an order of magnitude faster than the Datapoint I.
Gus and I argued for owning the rights to the microprocessor but at the time it was easer to upgrade the TTL version and by the time the 8080 was available we were working on a much faster processor.
Chapter 12 (Lamont Wood's book) is a good first person account of how the 8080 came about based on the Datapoint II processor design. (Less two instructions). Dave (Dave Monroe at Datapoint) wrote a translator that would run Datapoint software on the 8080 but it never gained any traction with management. Another dumb mistake.
The 8080 was approximately 100 times faster than the 8008.
This is significant step in function and solidified the microprocessors place in the history computing."

|Datapoint 2200 Patent|
Jack is referring to giving up the intellectual rights to the first microprocessor based on the 8 bit computer logic in the 2200. Datapoint contracted with Intel to design the logic of the 2200 into one chip for $50,000. However in the end Datapoint agreed to give the rights to Intel and did not pay the $50,000. This became the 8008 microprocessor and launched Intel into the very successful microprocessor business.

|Story by Lamont Wood|
Story by Lamont Wood. Lamont later wrote the book "Datapoint- The lost Story of the Texans who invented the personal Computer Revolution"
Lamont's book is very interesting and I recommend you read it if you are interested in the first days of the microprocessor and microcomputer revolution. More information here "CLICK" (Ed S thank you for this link.)

The email's from Jack Frassanito and Gordon Peterson gave me some great inside information about the Datapoint 8 bit computer story. I recommend reading Lamont Wood's book - lots of info about the development of the first microprocessor at Intel as well as the Datapoint story.
