  • Dave Tuttle's Memoirs
    Dave Tuttle Memoirs Page 1 DAVE TUTTLE’S MEMOIRS Melinda’s Preface Several years ago, when I was doing the research for an earlier paper, Romney White advised me to talk to Dave Tuttle, who had been one of the developers for VM/370 Release 1 and who had, like so many others, left VM (and IBM) when VM Development was moved from Burlington to Poughkeepsie. Like all the other advice Romney has ever given me, that was very sound. I quickly came to value Dave as an historian’s dream source, for he combines an astonishing memory with warm and witty perceptions. Over the past few months, as I’ve bombarded Dave with drafts of this paper, I’ve had the good fortune to be the recipient of several long notes containing reminiscences of his days working on VM. Having enjoyed his letters so much, I asked Dave to allow me to include them in this paper for others to enjoy. —MWV Dave’s Preface The time I was at IBM and involved with VM/370 was an important, and fairly intense, portion of my life and career. You may have, however, turned loose more than you counted on—by expressing an interest and being a good listener. Here are some of my recollections of “the early days”, from the point of view of a young participant.170 (In writing up these events, I am not trying to emphasize my own part in things; everybody was a hero according to normal IBM standards. The things that I remember most vividly are the ones that I was involved in directly.
