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

That looks a bit like a clone of the Term-Mite development
board for the NS405.
I suspect somebody just used the ADM-3A housing, monitor and
maybe power supply components
to hold their updated terminal.
