Okay, this is weird (I think!), but I need to source one to four Altek AC40 digitizing cursors, or even the parts that go into their making (ie, button pads). This is old stuff, circa 1985+, but essential when you've got the controller and table! My wife is on her last one at the Government of Manitoba's Conservation Department, and is desperate to get a few going for another year's worth of work! Any leads? Cheers, and thanks loads -- Jon.
