This post is to honour the one-year anniversary of the passing of Bill English, at age 91, on 26 July, 2020. English was Doug Engelbart’s right-hand man in the Mother of All Demos in 1968 and a key developer of the oN-Line System (NLS). The post below was initially part of a book I was writing about Engelbart. The book was eventually abandoned, but the memory of meeting English in 2014 remains. As does, I hope, the achievements of those SRI pioneers. RIP, Bill.

The report states that “the configuration of the ARC computer facility has been relatively stable over the past two years,” but there “have been some peripheral additions, in particular the ARPA network interface and an external core system.”
