Scope and Contents Division 6 Memo M-4160. Meetings between MIT-IBM personnel will be held periodically to discuss equipment troubles. This meeting was the first of the series; tape drive troubles and XD-1 maintenance policy in general were discussed. IBM believes that the practice of cleaning the tape mechanism every 8 hours will markedly reduce tape failures, which caused about 25% of all MIT lost time in January. It was agreed that Group 67 and IBM would work closely to try to determine the exact nature of...
