Recreates the circa-1990 AdLib OPL2 FM-synthesis sound card as a buildable open hardware project.

This is a self-assembly reproduction rather than a currently sold assembled card. The repository has no packaged release; use the project files and parts list directly.

Adds nine channels of OPL2-compatible FM synthesis to a Commodore 64 and can mix SID or other audio into its output.

The project page says all four production batches, totaling 360 cartridges, sold out. Commodore4Ever also showed its product page sold out on 2026-07-28, and Protovision's current music-peripherals category listed only FM-YAM cable accessories. Check the seller pages or used market for a restock.

An 8-bit ISA card with switchable classic sound-card modes plus MIDI, USB game-controller, and CD-ROM emulation.

Joe's Computer Museum showed the assembled PicoGUS 2.0 in stock on 2026-07-24. The official site also listed stocked UK and EU sellers. Open design files and build guidance remain available for people who want a DIY board.

Open ISA sound-card design using Yamaha OPL2 hardware for AdLib-compatible FM synthesis.

Retro Electronics listed the Version 1.2 bare PCB in stock on 2026-07-25. No components or assembly are included; the obsolete Yamaha sound chips can be harder to source than the common logic and passive parts.

Recreates the 1989 Sound Blaster 1.0 with digital playback and recording, AdLib-compatible synthesis, CMS audio, and a joystick/MIDI port.

This is a self-assembly project. Follow the documented bodge resistor, MIDI jumper-wire, firmware, DMA, IRQ, joystick, and I/O-address instructions before use.

Implements Sound Blaster-compatible audio for Micro Channel systems with OPL2 synthesis and CPLD-managed bus, interrupt, and DMA logic.

Installation requires the supplied ADF and the host reference-disk configuration program. The maker warns against LS or HCT logic because it may not meet Micro Channel timing margins.
