#KENSINGTON EXPERT MOUSE 7.0 TRACKBALL PC#

USB and Plug and Play has noy made my life easier. Actually I made it a RS485 to DB9 and I donвЂ™t need the phone jack if I had the pin connector diagram and could hardwire the stupid thing.

#KENSINGTON EXPERT MOUSE 7.0 TRACKBALL PC#

For you old PC geeks who understand, I need to use a non existent RS232 to make a RS485 into 2 bare wires. Now there all USB interface protocols instead of individualized, personal, one of a kind even made to order ways to address irq's 4 and 3. You could hook up a modem to it or a mouse its good for lots of things, like a RS485.

Is that really to much to ask for, just on simple comm port. I always thought a computer came with one serial. My newest computer doesnвЂ™t have a comm Port which I didnвЂ™t know until too late. From serial, PS2 and USB with forward and backward adapters in between, there must be a dozen I have collected over the last 25 years. ItвЂ™s the same trackball вЂdesignвЂ™ but over the years not only did the mechanical evolve to optical but the interfaces show the real evolution of peripheral connections over time. On another note, I have a box of some broken, some dirty and some just plain old, Expert mice. Someone on eBay has a listing for these trackballs for $86.24 delivered and he has 1,150 of them.ДЄt Amazon there the same price but they have a rebate for $15 dollars or %17, bottom line $71.24 to my house.Д¬urrently I am the high bidder on another listing for the Expert Mouse 7.0 and my decision will be made when the auction is over.
