Структурная схема калькулятора

Ввод — трафарет на матрице трубочек и кнопка «Ввод». Операнды от 0 до 99, операции + − ×. Схема разложена на 8 даёв по 150 элементов. Даи попарно собраны в 4 вертикальных блока, блоки стоят на объединительной плите с буферной полостью питания.

Сборка: 4 блока на объединительной плите

Questions

What parts does the Adder use?

18 parts. 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 Adder KiCad files?

From the radiolok/fluidicpc repository on GitHub, at the commit this page was made from: the board is verilog2netlist/FA_result/adder.kicad_pcb and its schematic sch/adder/4bit_adder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Adder design in my own project?

Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
