I have a quantity of ARC(E) Ltd. boards, from a complex calculator, or small computer. They are in CHesham, Bucks, UK, collection only. A small donation would be welcome, but I'm not that bothered. There are a couple of largish boxes of the things. They go for scrap in a couple of weeks, if not claimed. Jim. Please see our website: www.g1jbg.co.uk
