This is the service keyboard for all the machines in the adp folder.
It starts up but complains about the i2c eeprom being wrong/missing.

Picture, schematic and ROM (not by me):

Can it be made to write out a valid EEPROM? If so, we'd want to include that in the ROM set.

Also, how does this interact with the actual machines?

It plugs into the machine with a 6pin connector on a cable.
Wiping the EEPROM on a real one doesn't show the error message so I assume it can't detect it.
The EEPROM is used to save settings from one machine and apply them to others for when you have to set up an entire arcade hall.
If there is a way to write it out it's probably some key combination during startup, I tried to press some keys but I don't think they registered correctly.

Perhaps the eeprom is expected to be 1 filled to make it initialize?

	ROM_REGION(0x800, "eeprom", 0)
	ROM_FILL(0x000, 0x7ff, 0xff )

sadly didn't change anything

Just to be sure:

  1. you need to delete your existing eeprom file, in nvram directory.
  2. ROM_REGION(0x800, "eeprom", ROMREGION_ERASEFF) has same effect.
