VIC-II socket video coprocessor that adds programmable display effects, 512 KB of local memory, and integrated video cleanup to a C64.

The official project page remains online, but its Buy now area exposed no price, stock state, or working order destination on 2026-07-30. The last seller route found during this pass returned 404, and human review found no replacement seller, so confirm a current source before planning a purchase. BeamRacer also includes Lumafix Pro, software control of the HMOS-II gray-dot effect, a direct VideoMod connection, USB-C firmware updates, and the optional VBASIC development environment. Some narrow C64C boards may require a nearby capacitor to be resoldered for case clearance.

Socketed daughterboard that expands the C128 or plastic C128D from 16 KB to 64 KB of VDC video memory.

The maker's store exposed an active order path and reported stock on 2026-07-30. Installation requires removing the original metal heatsink and carefully extracting and reinstalling the MOS 8563 with the correct orientation. The maker recommends a modern low-profile heatsink because the daughterboard raises the chip. Reaching the VDC in some C128D systems may require removing the power supply, floppy drive, and drive controller.

Replaces all eight kilobytes of hot-running 6550 system RAM in an original PET 2001-8 with one open modern board.

The assembled Tindie board has been out of stock since 2025-08-04, but source, documentation, and design files remain linked from the product page. This is specifically for 6550-based PET 2001-8 system RAM and should not be treated as a generic replacement for later PET memory organizations.

No-solder SRAM daughterboard that expands a Commodore 16 or 116 to 64 KB and can switch back to 16 KB.

Poly.play listed the board as out of stock on 2026-07-30. The earlier direct AmiBay sales thread is closed. Use PCB revision 1.4 or later: the maker reported an error in revision 1.2, refunded those boards, and said revision 1.4 was corrected and tested with Diag264. A reset is required after changing the 16 KB / 64 KB selection.

Replaces the C16's original DRAM and multiplexers with a socketed SRAM module that can select 16 KB or 64 KB operation.

The maker's 2024 article still links a SellMyRetro offer and says kits are available, but current stock was not independently established on 2026-07-29. This is explicitly an expert installation: four ICs must be removed without damage, four sockets fitted, and A14, A15, and phi-0 signals connected. The maker warns that it is not a beginner project.
