  I can confirm.
  There are memory boards of the size described above and also smaller ones.

  The larger boards have two connectors so various combinations are possibl=
e:
- plug a smaller one onto the motherboard
- plug a larger one onto the motherboard
- plug a smaller one onto the larger and this onto the motherboard

  At least I could do this with the bunch of stuff I had (mixed DEC & Kings=
ton parts)=20
and  >>> TEST 50   succesfully identified them.
