The RAYDAC used 5,200vacuum tubes[3] and 18,000 crystaldiodes. It had 1,152 words of memory (36 bits per word), usingdelay-line memory, with an access time of up to 305 microseconds. Its addition time was 38 microseconds, multiplication time was 240 microseconds, and division time was 375 microseconds. (These times exclude the memory-access time.)[4][self-published source]
