Replaces the 74LS08 clock logic in Atari XL and XE computers with four separately buffered O2 outputs.

The product exposed a login-or-register-to-buy path on 2026-07-27. Installation replaces a 74LS08; a non-socketed chip must be desoldered and the required 14-pin socket is not supplied. The installer must identify the motherboard's actual CPU O2 connection by continuity rather than relying blindly on a model example. Three outputs carry 680 pF capacitors, while the uncapped top output is intended for Ultimate 1MB; remove a corresponding capacitor if a capped output causes instability.

Replaces aging Atari XL and XE power bricks with a regulated supply or a USB-powered DIN-7 cable.

Human review found both current variants sold out on 2026-07-24. Neither variant supports the 1200XL, 1400XL, or 1450XLD. Confirm connector, polarity, voltage, and current before powering a computer.
