Current FPGA replacement for MOS 6510 and 8500 processors, including the documented instruction set and cycle behavior.

The official project page links three current retail channels, and AmericanRetro exposed a direct Buy Now route on 2026-07-30. The retailer describes a same-size, no-soldering drop-in replacement; that assumes the original CPU is already socketed. A soldered CPU still requires proper desoldering and a suitable socket.

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.

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.

Historical low-power MOS 8701 replacement with separate PAL and NTSC versions and an onboard oscillator.

The original AmiBay sales thread is closed and its seller account has been deleted. No current direct order path was verified. TOLB was sold in separate PAL and NTSC versions, so identify the fitted variant and motherboard video standard before installing a used unit.
