-But why is this PC sound card interesting? In fact, they are the sound chip twice on the board : AY-3-8913, yes a version derived from the AY-3-8910. The Amstrad CPC is using the AY-3-8912 variant also used by the MSX (or its Yamaha variant the YM2149F), ZX Spectrum, Atari ST and Oric.

The Mindscape Music Board (video by The Oldskool PC) which appeared in 1986, a year before the Adlib sound card in 1987, which became a standard, followed by another standard with the Sound Blaster cards (1989). Only 2,000 cards were created at the time, and only four are believed to still exist today. The Mindscape Music Board was sold with the Bank Street Music Writer editing software, written by Glen Clancy, in two editions (one for the Tandy 1000 and PC Junior with just the software, and the other with a physical card for all other PCs with an 8-bit ISA card). The software was intended to be a word processor for music with 6 channels for notes and percussion, with octave changes, volume, envelope, and other features, with official music notation that could, of course, be printed. No MS-DOS game apparently supports this card due to its rarity, it losts foot when the Sierra company pushed the Adlibe sound card and the MIDI synthesizer Roland MT-32.
