Message-ID: <10158@rosevax.Rosemount.COM> Date: 21 May 91 13:37:20 GMT Sender: news@rosevax.Rosemount.COM Reply-To: craig@ernie.rosemount.com Lines: 9 I have some old 150ns 256x1 DRAMs and was considering picking up a 12Mhz AT motherboard and using them. What speed must the DRAMS be for a 12Mhz AT? Are wait states usually jumperable on the mother- board? Is there a simple formula to use to determine the required speed? Can slow memory chips be used as extended memory on a RAM card with a fast AT? Any help appreciated. Craig Taylor craig@ernie.rosemount.com
