Also, the Macintosh ports are convertible to Appletalk (which is a renaming of RS-485, as near as I can tell); they use 26LS30/26LS32 driver/receiver chips, both of which are also available from Jameco (under $2). Also listed as RS-422 driver/receiver are the MC3486 and MC3487, for $1.29 each (MC3486 is quad receiver, MC3487 is quad transmitter). The only relevant chips Jameco DOESN'T stock are the National DS36nn parts... John Whitmore
