Even though there are still a few unfinished projects lying around, I wanted to complete this Atari Jaguar mouse adapter before the end of the year.

Here’s a list of the things needed:

• A wiring diagram (Atari Jaguar Mouse Connector by Matthias Domin)
• A male DE9 connector (I had one left over from the CD-i null-modem cable)
• A male DB15 connector (make sure the middle row actually has all five pins)
• Flat ribbon cables, heat-shrink tubing, soldering equipment, etc.

Instead of a DB15 connector, I used a gender changer (male-to-male). It fits nicely inside the housing of the DE9 connector.

Heat‑shrink tubing is recommended for stability, since the wires are soldered directly to the pins of the gender changer.

This is the assembled adapter. For now, the wires hold the housing together and absorb most of the pulling force when disconnecting it. I doubt this will be its final form, though.

Here’s an Amiga mouse connected to the Atari Jaguar. Make sure to tell the software which mouse type you’re using (Amiga or Atari), because the wiring differs and they aren’t directly compatible.
