First off Welcome to the forum!!!!
Sorry but you will probably not be able to get a eeprom for that 1673S as it is
a very old drive and besides swapping one eeprom for another from a different
drive may or may not work usually it doesn't work correctly afterwords. :sad:
Each eeprom is set at the factory to match that one specific drive and when you
change to one from another drive it might just brick your drive. With the price as
cheap on new drives as they are now days you might just be a lot better off to go
and buy yourself a new faster/better burner. :iagree:
