Hi! Is there the network interface mentioned in "The User's Guide" on page 170. "Network, screened microphone cable via external MGT interface to Expansion Port." I think it must be a kind of concentrator. On next page there's NETWORK lead with title "FROM NETWORK PLUG DIN 7", so it doesn't mean SAM-to-SAM connection.
In MasterDOS description I found only 'DEVICE n', 'SAVE "n:"' and 'LOAD "n:"'. I tested this, but this is not network channels described in TUG on pages 118, 119 and 153. -- Yarek.
