Description
Firmware for a pool robot sold for home use from 1999, read from a unit retired by its owners.
Provenance
Sent to Lazarus by post, with a note asking whether anything could be saved. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. All files were recovered; 8 damaged sectors were rebuilt from redundant data.
