ABSTRACT:
A new host (14) and new PC card (12) are provided that have more than the standard two rows (16,18) of 34 contact positions each, where the new host can not only engage the new card but can also engage types I, II, and III standard PCMCIA cards so the new host is backward compatible to the large number of existing standard cards. The new PC card has the standard two rows (16,18) of 34 contact positions vertically spaced by 11/4 mm and has third and fourth additional rows (20,22) of card contact positions vertically spaced from the standard rows. The new card front end has laterally opposite card sides forming runners (44,48) of the standard thickness of about 3.3 mm, with the runners having upper and lower surfaces (72,74) lying respectively above and below the standard pair of rows, and with at least the third row lying above the level of the upper runner surfaces. The new host is similarly constructed with side runner guides (50,52) that guide the runners of the previous standard cards as well as of the new card, with the standard rows of host contacts being similarly positioned, and with the additional rows of host contacts lying above the runner guide upper surfaces. The third row (20) is preferably spaced (J) from the axes of one of the standard rows by more than the vertical spacing (F) of the axes of the two standard rows from each other.
