buss input
thingiverse
Most recent versions of all logics so far are available at https://www.thingiverse.com/thing:2829196, I recommend downloading from there. This 8-bit input/output bus logic allows inputs to be directed to the bus. Input A feeds into the bus, while input I is active when it's connected. Each register and ALU unit utilizes one of these buses to output data to the main bus. For further information on this concept, visit http://nextbigfuture.com/2016/04/molecular-mechanical-computer-design.html or http://www.imm.org/Reports/rep046.pdf. The SCAD file contains previously uploaded components. This design will eventually be parameterized and animated using OpenSCAD, but my current skills in this area are limited.
With this file you will be able to print buss input with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on buss input.
