TKII PS/2 Keyboard "Piggyback" Version WITHOUT PS/2 Connectors
The TK-II Series of interfaces will allow you to connect a PS/2 compatible keyboard to an Atari 8-bit machine. A new generation of PS/2 keyboard adapter boards allowing simultaneous dual PS/2 keyboards when combined with a Y-Splitter Cable*. It's designed to take over the duties of the stock keyboard in any Atari 8-Bit computer system, as well as the XE Gaming Console and the 7800XM. Giving you the flexibility and choice inherent in a multitude of PS/2 keyboards available on the open market. The TK-II can either take over completely, as is the case for the TK-II-GS model, or serve as an adjunct to the original stock keyboard, allowing both to work in concert. No matter which one you pick, all of the TK-II PS/2 keyboard adapters possess the same feature set and capabilities, with the only real difference being the way in which the board is meant to be installed. The Transkey board uses an embedded processor chip made by Microchip called a PIC, which runs a program that translates the PS/2 keyboard's serialized binary language into what the Atari's Pokey chip thinks are key presses emanating from the stock matrixed keyboard. You can use keyboard macros! All of your keys can be mapped to the external full size keyboard. For an XEGS, there is no modification required unless you want the four system switches (START, OPTION, SELECT, RESET) to be routed to the external keyboard
