Hi, here are some photos.
The first one is the SuperBase+Logistix dongle (completely ermetic!).
The second one is the Italy '90 Soccer dongle (note: it can't be inserted in the Amiga 600 joyport
).
The third one is the same, seen from the rear. It's full of some black resin. I suppose I could open the shell and then sink the black resin part in Acetone, but I fear that it could corrode the external part of the components...
Did someone ever managed to "decode" the Italy '90 Soccer dongle?
