Rebuilds a Commodore 64 around a preassembled replacement motherboard with automatic chip configuration, static RAM, flash ROM, and dual-SID support.

Individual Computers marked the board available for immediate delivery on 2026-07-27. It is not a complete computer: the key CPU, port, sound, and video chips are not included. The product page still uses some preproduction or older photographs, so physical appearance can differ.

User-port USB serial adapter for linking supported Commodore 8-bit computers to a modern host's virtual COM port.

The Tindie seller was taking a break on 2026-07-30 and did not expose an ordering path. GGLABS publishes a schematic, but the page does not present a complete fabrication and assembly package.

Business-card-sized RC2014-compatible Z80 computer with 1 MiB of memory and integrated serial and parallel I/O.

This is a surface-mount self-assembly project with KiCad, Gerber, CPLD, and firmware documentation. Programming its MAX7000AE CPLD requires the older Quartus II 13.0sp1 toolchain because newer Quartus versions do not support the device.

Bridges a modern computer over USB serial to Commodore IEEE-488 and IEC equipment, or supplies host-backed storage to a Commodore computer.

The maintainer explicitly calls XS1541 orphaned and reconstructed its documentation from an archived build guide. The surviving page provides a schematic, firmware, and detailed assembly and flashing steps, but not a turnkey current kit. The original board connector footprints are buggy: the narrow connector can short contacts unless the coding gap is physically corrected. A build also requires fine-pitch FT232RL soldering, ATmega programming, fuse setup, cables, and suitable host software.
