I'm looking to buy more memory for my SS1. Does anyone know: 1) does it use standard 1M X 8 boards? 1M X 9? same as IBM? Apple? 2) what kind of 4M boards does it use? 3) anyone know any reliable & cheap 3rd party vendors? w/ corporate rates? (Sun's list prices: 4M (4 1M boards): $1000, 16M(4x4M): $3500
