ZIP archive of 3.76 MB labelled for the Wacom DTH-W1310 pen display. The name gives no hint about its contents, which could be firmware, a schematic or service data for the device, so extract it and identify each file before use. For a tablet or pen display repair, such material typically helps with checking power circuitry, the controller board or reflashing a firmware chip. If you are flashing anything, read and keep a backup of the original chip first and confirm the hardware revision matches the files.
