D.9 AN APPLETALK NODE WITH THE MC68302 AND MC68195
The following paragraphs describe a hardware design that uses the MC68195 LocalTalk
Adaptor (LA) to interface the MC68302 to AppleTalk. The LA is designed to work directly
with the MC68302 for this purpose. The design is also suitable to those wishing to build a
proprietary HDLC-based LAN.
The design as shown works with a set of LocalTalk chip drivers, that allow frames to be sent
and received on the network. If these drivers are to be used, the interface between the LA
and the MC68302 must be identical to that shown in Figure D-32.
