Windows device driver information for CNet CN40BC PCMCIA Ethernet Card

The PCMCIA, or PC Card is a type of peripheral interface developed for laptop or notebook computers. The Personal Computer Memory Card International Association created the standard PC Card (and the subsequent ExpressCard). The US electronic computing industry founded the Personal Computer Memory Card International Association to vie with the JEIDA memory card device as a rival standard in memory cards. The JEIDA and PCMCIA standards later came together as PCMCIA 2.0 or JEIDA 4.1. The expansion of computer storage capacity was the primary reason behind the development of the PC Card, though numerous types of devices were compatible with this form due to an existing user-friendly standard for laptop peripherals. Conventional devices that made use of the PC Card technology included hard disks, modems, and network cards. The Kodak brand DCS 300 digital SLR camera series were among the devices which first utilized the system, although its current use for storage expansion is no longer in vogue.

A couple of type 2 slots (without barriers between them; thus permitting the insertion of two cards, or a single type 3 card twice the size) were incorporated into many laptops produced in the 90s. Legacy ports were subsequently removed, and many currently-produced notebook computers only have one type 2 slot. More and more inexpensive laptop computers do not have a provision for the PC Card slot. A PC Card device industry standard employs a 68-pin double-row interface. These interfaces are 85.6 millimeters in length and 54.0 millimeters in width – the size being identical to that of a credit card. The first standard was used in 5-volt and 3.3-volt cards. The 3.3-volt cards incorporated a safety feature which is a key on its side so that it would not fit into a 5-volt-specific slot. Many cards and slots were created to be compatible with both voltage formats. An improved 16-bit platform based on the ISA bus was the primary standard.
