I think that you misunderstand what is going on here. The normal mac to lw
connection is via a Localtalk NETWORK, not a serial cable. Not sure if just 
using the single DIN-8 cable will work, since I don't know if pins 2&3 need 
to be reversed (one man's send is another's receive). But you can get much
greater speeds with Localtalk (230.4 Kb/s if i remember correctly) than with
a serial connection (is 19.2 Kb/s max?). To make the network, you need the 2
boxes and the connector cable, though I'm not sure why it needs to be 2 meters
long.

see above
