[comp.sys.amiga.hardware] Mouse Systems M4 Conversion needed.

tscarpenter@brb.isnet.inmos.co.uk (03/15/91)

   Hello,

 	Can anybody help me ?
  
 	I have a mouse systems optical mouse (model M4), Thanks to Ed Hanway
     	I now have this working on my Serial port of my A500 but does anybody
  	know of a hack to enable it to work in the Mouse/Joystick port.
 
	I have a hack to convert a Mouse Systems Model 2/3 optical mouse to 
   	work but I think by looking at the conversion instructions and the 
  	inside of the mouse that the M4 is totally different to the M3/M2.
 
 	Thanks in advance.
	Darren Carpenter.

Can't be done. At least short of building it from scratch. Last weekend
I persuaded a friend to let me dismember his Boing! mouse in hopes that
I could easily duplicate that circuit for my M4 serial mouse.
Unfortunatly they use completly different PC boards, and different chips
(both labeled only with a Mouse Systems part number, and apparently
fabricated by VLSI inc.). It looks like the only way to get a Mouse
Systems M4 to work on the Amiga's mouse port is to buy the Boing! mouse
or buy the bus version and hack the cable.
