"The donor tells the story:"In 1979 or 1980 a friend of mine informed me that a friend of his was upgrading his computer at home and was selling his Apple 1. I did not ask if this fellow had purchased the Apple 1 new, but he was upgrading to a computer from a different manufacturer, possibly Alterra. I decided to buy this Apple 1 and the equipment he was using with it. While the Apple 1 looked like an amateur's assembly, the industrial surplus desk and integrated 19 inch equipment rack gave it a more finished overall appearance. The desk had a cutout with an IBM Selectric typewriter set into it. This Selectric could be used manually but was also configured for electronic control, and the interface from the Apple 1 was working.

I discovered that programming the Apple 1 to perform any useful tasks was a painstaking and laborious effort. The audio cassette recorder connected to the Apple 1 Cassette Interface provided the convenience of being able to reload the previous session, so software debugging could continue. I did get some experience with assembly language of a microprocessor. I also learned that I was not very good at it and did not really enjoy it. After about a year of periodic activity programming the Apple 1 I set it aside […] I disposed of the table with rack and Selectric, but kept the Apple as a possible historical item."
