Gravis Mousestick + GMPU Info

[antiriad76]

I have an old Gravis Mousestick programmable joystick which I had used briefly on my A500 in the Mid 90s. This is the same unit shown as here:

However I do not have access to the manual anymore and I have no clue how to program it.

When the device is plugged into the port is briefly displays "AMIGA" on the LCD Module before asking to center the joystick and press a button. From various post I found online it seems that pressing the 2 buttons on the left allows you to change between ATARI/AMIGA Modes but this doesn't do anything.

Also another post mentioned that that pressing 3 times rapidly one of the buttons will put the device into programming mode.

So far I haven't been able to locate any information on how to program this device. I only found a description of how the device operated on Amiga Format #014.

Any info will be appreciated.

Thanks
