Lets a 1088XLD emulate a joystick with its PS/2 keyboard arrow and trigger keys.

The project publishes schematics, Gerbers for both required boards, a bill of materials, and TK-II 2.7J firmware. A complete installation needs the piggyback board, interface board, ribbon cable, and programmed keyboard-controller firmware. The three auxiliary outputs are momentary open-collector signals and may need latches for some uses.

Adds an internal PS/2 or USB keyboard interface to supported Atari 8-bit computers by interposing at the POKEY socket.

Both variants exposed login-or-register-to-buy paths on 2026-07-27. A non-socketed POKEY must be desoldered, four control wires are required, and installation calls for a new case opening for the supplied keyboard socket or cable. The PS/2 page says an original keyboard that stops working on a 600XL or 800XL requires removal of R2 and R3; XE and XEGS machines leave those resistors intact.

Adds a PS/2 or PS/2-compatible USB keyboard to a ZX Spectrum 48K or Spectrum+ through an internal keyboard-interface board.

The seller exposed a login-or-register-to-buy path on 2026-07-27. It explicitly targets the 48K and Spectrum+ and warns that the original keyboard may stop working while the adapter is installed. The two signal modes use different motherboard signals; select the documented jumper state for the exact board and change hardware only with power removed. A USB keyboard works only if it supports the PS/2 protocol through its connector.

Lets Atari 8-bit computers use an external PS/2 keyboard through a POKEY-based internal adapter.

The Brewing Academy versions were sold out on 2026-07-24, while MyTek publishes schematics, board files, firmware, parts information, and bare-PCB order links. A 600XL or 800XL uses the TK-II-PB-R installation. Expect soldering and possible case modification; an unsocketed POKEY must be desoldered and fitted with a 40-pin socket. The Stereo version needs a second genuine POKEY and external amplification for its line-level output.
