Description
Control firmware for a telescope mount, read from the machine’s chips before it was scrapped.
Provenance
Deposited by Riverlands Software Preservation Group, which had held it unread for years. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. A handful of files survive, from a much larger whole.
