Ac64 is a way to use a good old C64 to learn Arduino (and Electronics in general). Why only to collect (or put it into basement) a c64 when it is possible to use it to learn (or simply to have fun) ?
Here there is a nice why to do that….
1) Arduino Uno R3 (Link)
2) Commodore 64 User Port Connector (*) (Link)
3) Container Box (**) modified to accept user port connector
4) Commodore 64 program manual (Link)
5) Connecting wire
6) Soldering iron
Instructions to build:
To build AC64 you need an Arduino Uno R3 (Genuino Uno R3), an user port connector.
Connect the Arduino directly to the C64 user ports (Tx,Rx) connector using the table below.
|Arduino||C64 User Port|
|GND||A & N|
|TX||B & C|
& meaning soldering with a wire, you can find user port description here
Instructions to load firmware:
There are some firmware (Serial control, webclient, lol) to load on AC64 to match right shield or right function. download it, and upload to Arduino following instructions on www.arduino.cc
Instructions to load and run c64 basic code
Download ac64.d64 and put it into sd card, loading it with hardware tool like sd2iec following user manual. After mount select program you need, according to right firmware loaded on AC64.
