Hi everyone, first-time poster and overall keyboard newbie here.
Just got a NIB Model M (a '96 42H1292 by Lexmark), and after plugging it in I was horrified to discover that some keys didn't work.
More concretely, these are the keys that don't register (tested with Aqua's KeyTest): B,N,Space,/,Right Alt, Left/Down/Right arrows, Minus on keypad
I first thought it was an adapter issue (I'm using a PS/2-USB adapter), but then discovered that tilting the board 45 degrees from the side and gently tapping it would enable these keys... as long as I don't put it back to horizontal.
I'm pretty sure this happened during shipping, maybe something unsoldered? Anyone seen this? If I were to open the board, what should I look for?
Thanks
Mauricio
