Hi!
This is a new thread dedicated to my BlasterBoard 2.0 project:
A modern Sound Blaster 2.0-compatible 8-bit ISA sound card for retro PCs.
The prototype looks like this:
It consists of 2 boards: DAC board (left) and OPL2 board (right).
The card supports playback of FM music and digital samples.
At this moment BlasterBoard 2.0 operates as SB2.0 in all DOS applications and games I tested it with.
Here is a short demo:

Unlike original SB2.0 card, BlasterBoard has an analog crossfader for manual
adjustment of FM music and digital sample playback levels.
Built on discreet 74HC logic, ATmega328P microcontroller, modern DAC and audio-grade
components in sound path for lowest possible noise and highest audio quality.
Done so far:
- FM music playback as Adlib (0x388) or Sound Blaster (0x2X8)
- 8-bit PCM samples playback in all modes
- Playback frequency from 4KHz to 96KHz
Still to be implemented:
- ADPCM playback
- Handling of sound recording commands (silent output)
