Jun 1, 2024 — by Giorgio Mendoza 235 views

HackerBox is a monthly subscription service that delivers development kits to hobbyists and students. The “Homebrew” themed HackerBox 0103 explores  the world of retro and homebrew computers, providing a nostalgic and hands-on experience in assembling and programming a computer from the earlier days of the personal computer revolution.

The main component of the HackerBox 0103 is the PICO-56 kit, designed by Troy Schrapel. This kit is a compact yet powerful homage to vintage computing, integrating components like the 65C02 CPU, a 65C22 Versatile Interface Adapter, and a TMS9918A Video Display Processor.

Users of the PICO-56 can delve into EhBASIC, exploring basic programming or loading various game ROMs, effectively turning the kit into both a learning tool and an entertainment unit. This capability not only educates users about older programming environments but also allows them to experience games from the past.

The assembly of the PICO-56 is a meticulous process, recommended to start with the trickier components like the MicroSD card slot, using tools such as the provided 951 solder flux pen. It’s essential to follow the assembly order and heed polarity directions to avoid common issues in the assembling process.

A key component provided is the Type-C Raspberry Pi RP2040 module, enhancing the classic design with modern connectivity. Before integration into the PICO-56, it is important to reprogram the RP2040 module to avoid hardware conflicts, particularly ensuring that the GPIO23 pin does not interfere with the operation.

The reprogramming steps involve using the BOOT and RESET buttons to enter bootloader mode, followed by loading the correct firmware according to the guide.
