Just today I decided to check out a local Value Village store just down the street from me....and when looking at the computer stuff, I see this model M-looking keyboard, but with a Dell logo on it.
Pick it up to have a closer look, weighs a ton, so I give a few keys a hit, and there is that familiar ping sound that we all recognize...turn over to see the label...says Model M, manufactured by Lexmark, 28-Mar-95, part #1369050.....and for the price asked...$5.99.....sold!
Take it home, plug it in through a PS/2 to USB thingy...works ok, and online reading tells me it is essentially an M keyboard..but the key caps do not come off as in a true M.
Good condition, no legend fading, works fully, but still needs a bit of a cleaning, all keycaps present...and I am typing this message on it.
A happy geekhacker here....
