PL/CBMBASIC is a PostgreSQL procedural language extension that integrates the original Commodore 64 BASIC V2 interpreter, allowing users to write database functions in BASIC with line numbers. It emulates the 6502 interpreter in C, provides validation for BASIC naming constraints, and supports OUT parameters by reading the emulated variable table.
The PD-64 is a compact USB PD replacement power supply for the Commodore 64, providing 5V DC and 9V AC using a USB PD adapter and a small planar transformer, with multiple safety protections. The project is open-source on GitHub with schematics and 3D files.
A detailed exploration of the unique font used in the C64 Dead Test diagnostic cartridge, including its character set, an Easter egg, and downloadable character ROMs.
Soul Player C64 implements a real 2-layer decoder-only transformer with ~25,000 int8 parameters in hand-written 6502/6510 assembly, running entirely on an unmodified 1 MHz Commodore 64 loaded from a floppy disk. The project includes training scripts to build and quantize custom models, assemble C64 binaries, and run inference at roughly 60 seconds per token.
