Gyropoint(tm) Mouse adaptor For those of you who haven't seen the Gyropoint(tm) mouse, it is a PC PS/2 or serial mouse which functions as a standard mouse on a desk, but can be used in midair simply by moving your hand. A friend recieved one of these from America as a Christmas present . But it didn't work with his Amiga :-( Sermouse didn't work, as it needed a separate 5V line for the gyros. This is a simple adaptor which allows the Gyropoint to work with an Amiga:-) Required : Sermouse software (ftp.doc.ic.ac.uk:Aminet/hard/drivr/22sermouse221.lha) 1 9-25 pin sub-d adaptor 1 5 pin DIN plug (as for PC keyboard ) 1 9 pin sub-d plug 2 core cable The Gyropoint comes with an adaptor to plug into a PC serial port and a passthrough plug for the PC keyboard socket. Simply wire the two plugs as shown,and connect the 5 pin din to the keyboard passthrough ,the 9 pin dsub to mouse port 1 or 2 on the Amiga , and the mouse adaptor to the serial port using the 9-25 pin adaptor. plug numbering: 5 pin DIN 9 pin dsub ------------- 2 \ 5 4 3 2 1 / 5 4 \ 9 8 7 6 / 1 2 --------- 5 pin DIN 9 pin dsub 4-------0V------8 5-------5V------7 Then run sermouse , and it works! Alternatively, you could build a 12V-5V stepdown cicuit into the 25 pin plug shroud. Disclaimer: if this adaptor sleeps with your dog , bites your wife , or chases your sheep, don't blame me . ALWAYS double check your connections. Leo Maxwell Birmingham UK hammer@enterprise.net
