Hi folks,

A friend of mine has said ADM-3A and is baffled by the tiny board it contains, 
not the usual ‘covering entire base’ discrete logic board they normally have. 
Centre of this board is the Nat Semi NS405 ‘display processor on a chip’ which 
is obviously why the board is so small but neither of us have seen this before 
in a 3A.

Anyone else? Pic at http://www.binarydinosaurs.co.uk/tonyADM3a.jpg
