Creative Labs Sound Blaster AWE64 Gold with 8MB RAM expansion [CT-4390 + CT-1930]

  • Music capabilities: 20-voice FM OPL3 emulation (Stereo)
  • MIDI capabilities: 64-voice E-MU EM8000 (1MB ROM) (Stereo) *
  • Digital capabilities: 16-bit/44.1kHz Playback, 16-bit/44.1kHz Recording (Stereo)
  • Other: 4MB on-board RAM (expandable to 28MB with proprietary Memory Upgrade Modules) **
  • Connections: Line-out, Line-in, Mic-in, Game-port (doubles as MPU-401 UART interface)
  • Interface: ISA (16-bit)
  • Year of introduction: 1996

*    32-voice hardware based, 32-voice software-based, relying on system CPU
**  A modern upgrade board called SIMMconn exists, allowing to upgrade the memory using regular 72-pins SIMM modules


LABS Blasterboard (DIY Kit)

  • Music capabilities: 11-voice FM Yamaha YM3812 OPL2 (Mono)
  • Digital capabilities: 8-bit/62.5kHz Playback (Mono)
  • Connections: Line-out
  • Interface: ISA (8-bit)
  • Year of introduction: 2019

*    This is a custom-built Sound Blaster 2.0 clone specifically designed with low-noise in mind. It lacks the game port as well as line/mic inputs but does have a PC-speaker and CD-Audio header and separate volume buttons for all sound sources at the back. The card is based on a real Yamaha OPL2 chip and an Atmel Atmega328P microcontroller.


Roland RAP-10 Audio Production Card (Boxed)

  • Music capabilities: 26-voice Roland General MIDI (128 instruments, 6 drum kits) *
  • Digital capabilities: 16-bit/44.1kHz Playback, 16-bit/44.1kHz Recording (Stereo)
  • Connections: Line-out, Line-in, Mic-in, Game-port (doubles as MPU-401 UART interface)
  • Interface: ISA (16-bit)
  • Year of introduction: 1994

*    26-voice polyphony is actually what the box tells. Probably 2 voices are lost on behalf of the digital audio capabilities. The GM soundset is the same as the Roland SC-7 Sound Canvas.
