I would like pugrading my vaxstation 4000/90 from 16 Mbyte to 32. To my understanding you have to fill the slots (8) with always 4 identical memory banks. I have already bought 2 * 4 Mbyte ram banks and need two more. In case someone has two for selling, please let me know Frank PS: I saw a vaxstation 4000/90for > 350 USD at ebay, can't believe such high price
