Claim 5

Independent Claim 72 words

A method for interfacing a standard peripheral device to a computer via a PCMCIA bus, the method comprising the steps of: a) driving data to be written to the peripheral device on the PCMCIA bus; b) extending the time the data is available to the peripheral-device on the PCMCIA bus for a period sufficient to satisfy the timing requirements of the peripheral device; and c) writing the data to the peripheral device.

Claim 6

Independent Claim 72 words

A method for interfacing a standard peripheral device to a computer via a PCMCIA bus, the method comprising the steps of: a) driving data to be written to the peripheral device on the PCMCIA bus; b) extending the time the data is available to the peripheral-device on the PCMCIA bus for a period sufficient to satisfy the timing requirements of the peripheral device; and c) writing the data to the peripheral device.

Claim 7

Dependent Claim 23 words
