Not sure that Euro or Phoenix connectors were around (or at least readily available) when these beasties were built. Strictly 1970's low tech.

Shall we say less than "best engineering practices". And... Consideration to rack placement is critical. If access to the Logitek's top cover is needed for maintenance and its obstructed, it means removing every single wire to an array of screw-down barrier strips. A better solution for Logitek would have been to design a back-plane using miniature Euro-Block connectors so that groups of plugs can be unplugged from a mating barrier jack. Need to remove the mixer from the rack? No problem. Just unplug a few connectors and reconnect when maintenance is complete. For most equipment, removing a few wires is not problematic. But when you consider the number of possible connections on the Logitek back-plane, removing every wire can be a nightmare. Fortunately for amateur radio purposes, not too many of us need a lot of inputs -- unlike typical remote broadcast demands.
