Does anyone know if the connectors on the cables are
still obtainable?
The ST506/412 drives had card edges on the PCB for the cables. Since PCbs
are still being made, you can presumably still etch suitable patterns
of fingers for this.
The edge connectors to mate wit hthose (used on the drive end of the
cables), the 2-row hearer sockets (used on the controller end of the
cables in many machiens) and the header plugs that were then sodlered to
the controller board are still, AFAIK, made adn are available from RS
components, Farnell, etc.
