Newton to Amiga cable

(in reply to a letter from a person who had previously used Emplant succesfully with his Newton using the Appletalk protocol. Unfortunately, although Emplant worked with his A3000, it did not work with his A3000T. Now he is using ShapeShifter, but the cable he was using previously did not work...)

Thanks for mailing your cable configuration.  It does differ from mine.

Here is my cable... (which came with Newton Connection Kit for Windows).

Here are the connections between SUB-D9 to Mini-DIN8

(The above came courtesy of thorin@ods.de, whose ShapeShifter
 and Newton combination is now working as well).

The above cable is in fact a null modem cable. It could not without modification, for example, be used to connect a Newton to a modem.
