As I understand it, the appleshare/appletalk port on a IIgs requires custom hardware to handle the encoding/decoding of the signals. Or is it just a standard UART with a high data rate and special logic/ firmware to handle the decoding?
Definitely not a standard UART. Isn't it some flavor of NRZ encoding?All the Localtalk adapters I'm familiar with used a particular Zilog chip for the phy interface.
