Some of them had four pins,  and some had seven,  but the receptacle was
always a 7-pin DIN socket.  Also on the VIC20,  though some of the earlier
VICs used a 2-pin power connection.

Having scrapped a bunch of that stuff,  I have lots of 5, 6, 7, and 8-pin
sockets to use for stuff.

The only place I've seen them loose is at hamfests,  and I snagged a couple
some years back,  handed them off to this other guy to put wires on them. 
I'm sure that Switchcraft and other major connector makers have them
available.
