Models 60, 62, and 70 were announced in April of 1964. During
development, they improved the designs enough that they substantially
exceeded the promised performance, and eliminated the reason for having
separate models 60 and 62. Rather than introducing the machines under
those previously announced model numbers, which would have led to
confusion regarding the specs, they announced them as the models 65 and 75.
