摘要: A data processing system including a bus (ISA, EISA), in which address lines (SA) and (SD) are connected parallel to series of slots for receiving, each, any one plurality available extension cards. Control the slots, except at least specific control line (AEN, SMEMR#) operable enable slot by rendering accessible, through bus, circuits card inserted slot. The further includes means (A, S, 30) programmable transmitting state predetermined slots.
