Firmware dump for the NEC LCD 1770V monitor, compressed as a zip and tied to an SST39VF020 flash chip with a 256 KB image. The SST39VF020 is a 2 Mbit parallel flash, so it needs a programmer and adapter supporting that package rather than a simple SPI clip. Use the file to restore scaler code when the monitor shows no image or malfunctions after corruption. Back up the original chip first and check that its marking and capacity match before writing.
