64kbvdcvideo memoryinternal upgradesocketed modulesolderless

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.

Compact, low-power C128 VDC video-memory expansion built around one 64 KB static RAM chip.

Poly.play listed the pxlmod board as out of stock on 2026-07-30. An older Protovision order link now reports that the product is not found, so check Poly.play for a restock. Current wording names the Commodore 128(D) without separating plastic C128D from metal C128DCR; the latter normally already has 64 KB of VDC memory.
