A word here is 28 bit, against the Apollo Guidance Computer's 16. Word counts from machines with different word widths are not a like-for-like capacity comparison. |

Editorial notes
Between one and eight modules could be fitted. Eight in simplex give the maximum 32 768 words capacity; running them in duplex trades half the capacity for redundancy.
