Transistorized modular power supplies for digital computers
Theodore C. Gams · 1958
Power supplies for digital computers are characterized by unusually rigid reliability requirements. After reliability, size and cost are the next most important considerations. Simplicity of design and ease of servicing are considered as part of the reliability problem, since computer down-time, particularly in large installations, may cost from $10.00 to $100.00 per minute. In military digital computers, reliability may be of incalculable value.
