Classes/Building an 8-Bit CPU from Scratch (view source)
Revision as of 18:41, 31 May 2017

==== Components ====
==== Components ====
The following components are required to build the CPU project. No components are "consumed" by this project, as long as it is built on a breadboard; so, if you so choose, you may reuse these components in future projects. A bulk-purchase option is given to students at the beginning of each class, which serves to reduce costs. The average cost, per-student, when bulk-purchasing all-new components is generally about $TBD.

<small style="display: block; width: 75%; min-width: 350px; margin: 25px auto;"><i><sup>†</sup> For advanced participants familiar with soldering, [http://amzn.to/2s1W7xR StripBoard] can be used instead to save space and money (about $30 in savings). Do note, however, that soldering and organization of these boards will not be covered in the class, and if chosen by the student, will need to be managed themselves. Using such boards can also make debugging and modification significantly more time-consuming and difficult. If using StripBoard, ensure that the board's [[Wikipedia:List of integrated circuit packaging types#Dimension_reference|pin pitch]] is the standard breadboard size of 0.1" (2.54mm).</i></small>
