The computer's RAM was magnetic core memory (2 kibiwords, where a kibiword is 1,024 words) and ROM was implemented as core rope memory (36 kibiwords). Both had cycle times of 11.72 micro-seconds. The memory word length was 16 bits: 15 bits of data and 1 odd-parity bit. The CPU-internal 16-bit word format was 14 bits of data, 1 overflow bit, and 1 sign bit (ones' complement representation).
My cell phone has about 20 Megabytes of user memory available, which is several thousand times the storage capacity of the AGC's RAM.
leading bit lsd or msd?
