Dongles for Amiga Scala MM

'tis annoying how people will sell, or give away, their Scala software but not include the dongle along with it.  Or, you lose your own dongle.

Red dongle, from Scala MM 200 (*?)

10kΩ resistor between pins 6 & 9
100kΩ resistor between pins 8 & 9
10μF capacitor between pins 8 & 9 (positive towards pin 9)

The original has a tantalum cap, marked 106, but any type of cap should do.

(* I'm not entirely sure of the colour, nor which version it belongs to, but we were given the box for Scala MM 200, with discs and manual in it, and found a stripped dongle with red resin on the inside, elsewhere in the collection of computer bits and pieces.  We bought Scala MM 400, and its dongle has a green outer rubber and green inner resin around the pins, so I'd guess they do the same thing with other dongles, and this dongle belongs to 200.)

Green dongle, from Scala MM 400

10kΩ resistor between pins 6 & 9
100kΩ resistor between pins 8 & 9
470nF capacitor between pins 8 & 9 (positive towards pin 9)

The original has a tantalum cap, marked 474, but any type of cap should do.

The dongles are a male and female connectors, soldered together as a pass-through, so that other peripherals can still be plugged into the same port.  But if you don't need the pass through, just fit the parts into an ordinary female connector's backshell.  And if you don't like having huge great dongles poking out the back of an Amiga 1200, then make a short flylead with a low-profile IDC connector, and thread it inside the Amiga casing, so the dongle components are inside the computer (insulate it and fasten it in place, too).
