Parallel Bus Interface, złącze używane w [[600XL]] oraz [[800XL]]. Złącze ma 50 linii i służy do podłączania urządzeń zewnętrznych (tzw. [[Nowe urządzenia|nowych urządzeń]]) jako forma portu równoległego. Autorem koncepcji PBI jest Earl Rice. Komputery serii [[XE]] są wyposażone w nieco odmienne (inny kształt, nieco inny zestaw sygnałów) złącze tzw. [[ECI|CART/ECI]] będące rozwinięciem PBI.
