An adaptor cable is required to connect a pair of LK keyboard and VS
mouse to DB15 port of 3MIN/3MAX+.  The same adaptor is used for
TURBOchannel Alpha machines DEC3000 and possiblily late models of
VAXstation family.  You would be able to acquire it asking excesses to
port-vax or port-alpha mailing list.
