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.

• ISA expansion boards Bus/interface

Recreates the Gravis Ultrasound PnP ISA sound card around an AMD InterWave chip, with an optional IDE CD-ROM interface.

The maker has not fabricated or tested this board and has not generated a fabrication package. It also requires an AMD AM78C201 InterWave chip. Treat it as an experimental design and build at your own risk.

• ISA expansion boards Bus/interface

Provides MDA and CGA-compatible display modes with 31 kHz VGA output for modern monitors and capture devices.

This is a self-assembly project. The maker advises checking for shorts between each power rail and ground before installation; the oscillator configuration also affects CGA composite color accuracy.

• ISA expansion boards Bus/interface

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.
