Description
Control firmware for a drum machine, read from the machine’s chips before it was scrapped.
Provenance
Deposited by Riverstead Games Museum, which had held it unread for years. The controller had failed, so the memory chip was removed and read directly. All of the work survives. The repairs are listed in the record’s damage map.
