If you have unused connectors on the ribbon cables (e.g. last memory
board not instaled) just use a suitable male connector for the ribbon
cable, solder the resistors to it and connect it to the last, unused
connector of the cable.
If you need all connectors on the ribbon cables make a new cables with
one additional connector, then see above.
Use a male and female connector, solder the pins at the tips together,
so that you get a 1:1 male-female connector. Solder the resistors to the
sides of this.
All of this is not hard if you know how to handle a soldering iron. I
build SCSI terminators that way.
