Description
===========
The DEFEA-DA is a two-card, dual attachment station (DAS) adapter with
multimode optics and ANSI MIC connectors which provides direct connection of
industry standard computers with an EISA I/O bus to a 100-megabits/second
(100 Mb/s) FDDI network. The two cards, a parent card and a daughter card,
are connected by a ribbon cable and plug into adjacent computer slots on the
EISA bus.
Features
========
The main features of the DEFEA-DA are as follows:
1 megabyte of packet memory
68000 onboard processor
DMA control
EISA bus interface control logic
FDDI interface chipset
FDDI optical interface
IEEE address ROM
Onboard, nonvolatile memory for firmware storage
