Description
Control firmware for a telescope mount, read from the machine’s chips before it was scrapped.
Provenance
Donated by the creator’s family in 2007. The card had sat unpowered for years; it was read at low voltage, several times. Everything was recovered, with a few damaged files repaired from a second copy.
