Questions
How big is the LogicBoard 3GE Repro PCB?
It measures 208.4 × 105 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LogicBoard 3GE Repro use?
169 parts, built around the LM386, 74HC74D, CD4052BM and MC14081B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LogicBoard 3GE Repro KiCad files?
From the tullulah/VectrexPCBRepro repository on GitHub, at the commit this page was made from: the board is LogicBoard 3GE Repro/LogicBoard 3GE Repro.kicad_pcb and its schematic LogicBoard 3GE Repro/LogicBoard 3GE Repro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LogicBoard 3GE Repro design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
