  A high density diquark phase seems to be a generic feature of QCD. If so it
should also be reproduced by random matrix models. We discuss a specific one in
which the random matrix elements of the Dirac operator are supplemented by a
finite chemical potential and by non-random elements which model the formation
of instanton-anti-instanton molecules. Comparing our results to those found in
a previous investigation by Vanderheyden and Jackson we find additional support
for our starting assumption, namely that the existence of a high density
diquark phase is common to all QCD-like models.
