CRG | Building and testing a SID chip expansion for the Sinclair Spectrum. @CRG | Uploaded May 2024 | Updated October 2024, 2 hours ago.
Two of the most infamous computers of the 1980s brought together over music. In this video we attempt to build a SID expansion for the Sinclair Spectrum and try to get it playing a few SID music files.

Massive thanks to SparxUK for kindly donating this project.
Additional thanks to @YawningAngelRetro for letting me hold onto his 128k for this build.
