hi
i was canalizing a old mouse to fix the mouse i use the most and i noticed these ps2 mice have a chip in each one. is there anyway to identify these two chips one is from a Microsoft mouse and the other from a logitech mouse and both are quite old ball type seems a shame to just throw them away

 

Probably a custom chip MSFT is Microsoft's ticker symbol.

 

It would be a worse shame to keep them forever.

When the zombie apocalypse hits and all that works are the old microsoft mice, who will be laughing then?

 

smiling
well if old electronic parts will save me then i'm safe i save everything, i might not be able to FIND IT but i have it some where around here lol

i was just wondering it they could be wiped and reprogrammed is all.

 

For chips like that which are made in millions they will be manufactured as they are, there won't be any programmable or reprogrammable areas. Maybe you could connect it as it is to the PC and use it as a dual frequency counter.

 

wonder if you could hook it to an arduino for a position censor for a small bot

 

Could be. Keep the chip, sensors, slotted wheels and anything vital and you have a 2 channel, serial output rotary encoder.

praondevou but it still looks like isn't able to be erased and reprogrammed that is what i was trying to do recycle the chip into something else.

this is really interesting also
