This job needs some Laptops icorporating into the the network. Thought I had nothing to do but couple in using PCMCIA (PC Card) Cards.
Q. Is there Two types of PCMCIA Networking Cards as the one's we bought in don't fit, a thicker plastic lip prohibits them from inserting correctly. If we bought the wrong ones what should we be looking for ?. the first cards were 3Com 10/100 base.

It would be nice to know the make and model of the notebooks you are trying to network. Larry

Thanks again Larry....

Thought I'd answered this.. Right, what's to network is a couple of IBM Thinkpads at P100 spec and a couple of MITAC 5023 P133s All have PCMCIA Slots.

The Cards we bought DELL 3CCFE575BT 10/100Base. They fit our Twinhead and Tiny Laptops no bother and work quite well.

PCMCIA cards come in three form-factors:

PCMCIA (original) 3.3 millimeters thick
PCMCIA II 5.0 mm thick
PCMCIA III 10.5 mm thick

All three have the same length and width

Types II and III come in 16-bit and 32-bit versions. The 32-bit versions are known as a CardBus PC Cards. 16-bit versions are PC Card-16 PC Cards. CardBus cards can only be used in notebooks equipped with CardBus slots.

http://www.kingston.com/networking/adapters/cb4tx.asp: “PC Card-16 cards use an 8- or 16-bit interface that operates at ISA bus speeds (8 MHz) using an ISA-like asynchronous protocol. In contrast, CardBus provides a 32-bit multiplexed address/data path, which operates at PCI local-bus speeds of up to 33 MHz, yielding a peak bandwidth of 132MB/sec. CardBus accomplishes this by adopting the synchronous burst-transfer orientation of PCI, as well as a bus protocol, which is essentially identical to that of PCI.”

The Mitac 5023 (http://www.mitac.com.hk/notebook/) has either two type II or one type III PCMCIA slots. There are many variations of thinkpads… They have one type III or two type I/II. The Dell/3Com NIC (http://support.3com.com/infodeli/tools/nic/3ccfe575b/docs/ug/index.htm) is a type II 32-bit Card Bus card.

I suspect you need the older 16-bit PC Cards, such as the 3COM 3CCFE574BT (http://www.3com.com/mobile/pccards/3cxfe574btsp.html).

See http://www.pc-card.com/pccard.htm, http://www.rdrop.com/~cary/html/pc_card_faq.html, and http://www.xircom.com/cda/page/1,1298,0-0-1_20-403,00.html#q1 for more info. Larry
