Retains the original POKEY while adding FPGA stereo POKEYs, Covox channels, digital mixing, and a high-rate stereo DAC.

The product exposed a login-or-register-to-buy path on 2026-07-27. It requires a working original POKEY and can be installed in stages: basic stereo output, a second POKEY through an A4 connection, Covox through D6xx or D7xx decoding, and full internal-audio mixing. The approximately 1 mm PCB intentionally leaves pin 31 unconnected; verify that it remains isolated from the motherboard. Only the basic stage uses a single address jumper, while the expanded functions require additional signal and audio wiring.

A family of SD multicarts for Atari 8-bit computers, ranging from cartridge loading to disk, tape, memory, clock, and audio expansion.

All three product pages showed In stock and Add to cart on 2026-07-24. Optional SIO, ECI, PBI, and DAC cables are separate. SUBCART's extra functions need ECI or PBI, and the maker does not recommend them on a machine with U1MB or another third-party internal memory expansion.

Replaces a failed or missing Atari POKEY with an updateable FPGA module in the original DIP-40 socket.

The product exposed a login-or-register-to-buy path on 2026-07-27. Installation is solderless only when the computer already has a compatible DIP-40 POKEY socket. This is a functional FPGA replacement, not a transistor-level NMOS clone; the seller warns that software depending on undocumented analog behavior or exact electrical characteristics may behave differently. The built-in USB port allows future firmware updates.

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.

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.
