The Suntronics KD-81 Keyboard is a fully cased keyboard with full-size keys, including 2 shift keys, and a space bar. The printed circuit board from the computer fits inside the new plastic keyboard’s vaporized metal coated case. Assembly requires attaching the PC board inside the case with 5 screws and slipping the keyboard’s ribbon cables into the computer’s 2 keyboard sockets. After using the keyboard for one month, I find it works great and is easy to assemble and operate.
