Hi, it is a custom PLCC chip, I have an EPROM burner already - this ones a bit more specialised. When I say trade in the opening add - I mean I have a UMK3 board with pretty much all the bits on it security chip, EPROMS, etc. This board is complete but damaged. I haven't attempted to repair it. I do know that this particular board damages U45 chips, to my great annoyance. I broke a golden rule in haste - you live, learn and grow wiser. I have other boards particularly Mortal Kombat Boards 100% working or other parts, if required. I'm open to suggestions - but I live in the UK.
