<blockquote> | |||
But Howard then threw another challenge to his group: plug-in height. | |||
Work up through late 1966 had assumed a seven inch plug-in height | |||
which would provide room for the needed components using readily available and proven parts. | |||
But the H-P scopes were smaller in size and quite attractive in appearance. | |||
So, one day, Howard said, "the plug-ins will be 5 1/2 inches in height." | |||
Oliver Dalton recalls the decision to reduce the plug-in height as a traumatic one: | |||
"The decision set us back at least one year for the height decision required three major electro-mechanical component efforts in addition to the IC read-out effort: 1) new lit push-buttons. . .we needed 25 on a panel; 2) cam switches-these were Howard's ideas. . .we needed them to be small and reasonably cheap; 3) relays. . .we needed them to be small and reliable. We then largely had to make do with other available parts, like potentiometers." | |||
