Cartridge-port prototyping board with a mini breadboard and jumper leads for building C64 circuits.

Poly.play listed SKU PP0057 at EUR 17 including German VAT but marked it out of stock on 2026-07-30. The page publishes no schematic, pin map, design files, license, buffering, isolation, fusing, current limit, or power-handling specification. Confirm a restock and treat every computer signal and power line as unprotected.

Historical breadboard adapters for prototyping through a Commodore control port or the VIC-20 expansion port.

C64 OS preserves the former $13 joystick and $19 VIC-20 listings, but no current product was exposed on Dorktronic's eBay profile in July 2026. The joystick item URL also failed two Tavily extractions after the required 60-second retry and is logged as WF-062. Treat both boards as used-market finds. Documentation was not included. Both designs expose computer power and signal lines directly; the VIC-20 feature explicitly warns that improper prototyping can damage the computer.

Compact cartridge-port prototyping PCB and breadboard-bridge kit for C64 hardware development.

Both email-order pages were last updated on 2025-01-01. The kit page then claimed stock, while the version 2 page gave no price or stock quantity. Neither page exposes a checkout route, pin map, schematic, design files, license, board-revision comparison, protection details, or complete included-parts list for a bare version 2 board. Confirm current availability and the exact PCB revision and package before ordering.

Provides a reusable prototyping card with an in-system programmable ROM for Apple II and Apple III hardware projects.

The current storefront exposed kit and assembled selectors on 2026-07-24. It is a development platform, not a finished peripheral; safe use depends on the user's circuit, firmware, power handling, and bus design.
