CoPiCo PCB KiCad Files

The CoPiCo is a cartridge for the Tandy Color Computer that adds WiFi to and serves as a boot ROM for the system. It is based on the Raspberry Pi Pico W microcontroller dev board, which includes onboard WiFi.

WiFi Connectivity

The firmware (see 'copico-firmware' repo) will behave more like a SPI WiFi module or the WizNet chip (or perhaps both, depending on mode). It will, of course, also allow listing and connecting to the desired WiFi network.

ROM Emulation

CoPiCo will also support boot ROM emulation (initially just for a 1 KB ROM due to limitations of first revision of the CoPiCo PCB). Henry Strickland (@strickyak) plans to use this feature to load a version of his "axiom" network boot ROM (see https://github.com/strickyak/frobio/tree/main/frob3/booting).

Other Future Capabilities

Future capabilities for the CoPiCo may include:

• VGA or HDMI output based on the captured contents of video RAM
• Logic capture / bus trace
• Remote debug, with breakpoints and watchpoints
