Atari antic switch
About the Atari antic switch PCB
Atari antic switch is an open source PCB design by owen-rp2a03, published on GitHub under the MIT license. It is a 2-layer board measuring 47.2 × 53.3 mm, with 10 components from 8 distinct parts.
Other key parts include the ANTIC_NTSC, 74LS245 and ANTIC_PAL. By type, the board carries 4 ICs, 4 connectors and 2 resistors.
From the project
Atari 8-Bit Antic switch
Uses two '245 transceivers and holds reset on either Antic to disable them; isolating the control signals may not be necessary but doing it just in case. Too many wires and two dip-40 chips for me to reliably test on cheap breadboards, so designed a theoretical circuit for a prototype pcb.
2026-5-28 - Boards recieved from PCBWay, confirmed not working, signal directions through bus tranciever need reworking due to my uncertainty of the i/o of the control lines for Antic.
