#21855 - RE: Read-write signals |

PSEN was connected to "dis-able" the decoder during a code fetch as RD & WR were not included in the decode so these devices would have been enabled during a code fetch (using power not otherwise required). As to alternative decodes the dual '138's were a given. regards, p |
