MISCELLANEOUS NOTES

The PC adapter can be used in a file server or a work station while the PC-WS adapter can be used in a work station only. Different drivers must be used for the National & the Fujitsu chipset cards, they are not interchangeable. Fujitsu adapters may be used for either 8 or 16-bit Fujitsu cards, while the National chipset cards require a different driver for an 8 or 16-bit card.
