Other key parts include the 74LS245, 74LS374 and 74LS138. By type, the board carries 16 resistors, 8 switches, 8 diodes, 4 ICs, 4 connectors and 4 capacitors.
It belongs with the retro computing designs in this gallery.
From the project
An expandable SBC-version of the Apple 1 computer, easy to get started with and lot of cool stuff that can be added to it!
Since building and spending time with the excellent RC2014 computer kit, I wanted to build another one from scratch while learning even more about them along the way. Combine that with the love of old machines I'll never be able to own, and the missing knowledge to actually do that I instead started looking for books on how things work on a more basic level.
