Proposal for Reducing the Number of Tubes Used in Driving a Magnetic Matrix Switch
(MIT Digital Computer Laboratory, 1953-06-17)
There are two independent questions that must be answered when choosing a switch operating mode:
1. Should the "set" and "reset" windings take part in the selection operation?
2. Should the "bias" drivers be gated?
