The IBM Model M 1391401 Buckling Spring Keyboard is a brand new mechanical keyboard with a QWERTY layout, designed for use with PS/2 wired connectivity. It features a classic white color and is made in the United States. This keyboard is ideal for users looking for a high-quality, durable option with a familiar layout and reliable connectivity. I bought this new, but ended up never using it. It comes with a PS2 to USB adapter. It comes inside a custom styrofoam mold that fits the keyboard perfectly.
