Unquestionably, a lot of fun! + +Armed with the knowledge from building that kit I decided to attempt to create +one myself, lack of knowledge when it comes to circuit design and pcb layout +aside shouldn't be a problem right? Not as long as you enjoy tinkering with stuff. + +The RC6502 is that kit, and since I wasn't yet born at the time and therefore did not +own one I decided to create a working replica of the Apple 1 computer. The original +schematics are readily available on the Internet - as is also an excellent book on the +topic; [Apple 1 Replica Creation, Back to the garage](http://www.applefritter.com/) by +Tom Owad. + +I've been documenting the build process of the various components on my blog at +[https://hvetebolle.blogspot.no/p/rc6502.html](https://hvetebolle.blogspot.no/p/rc6502.html), +but be warned that it's in my native language (Norwegian) so this might not be +anywhere close to readable for most people. + +![RC6502 Computer](https://raw.githubusercontent.com/tebl/RC6502/master/Gallery/2017-06-02%2019.54.19.jpg) + +## Modules +Like the RC2014 I've decided to keep things very modular with each card more or +less doing one simple thing, easier to wrap ones head around as a beginner and +much easier to understand - also a lot cheaper to upgrade or replace since you +don't need to replace the entire thing. Note that I haven't decided on designing +my own backplane, mainly because the RC2014-version works really well (see RC2014 +tindie page for ordering) and I've already got it. + +In order to use the RC6502 you'll need the following modules: +- Backplane (see RC2014) +- CPU +- RAM +- ROM +- Reset Circuit +- Serial IO
