Parity RAM is 9 bit RAM instead of the normal 8bit RAM. The 9th bit is used to check for 1bit errors. >Can I use regular 1 Meg SiMMs (80 ns) in a Mac II ci? If you have a normal II ci, you should use regular SiMMs. If you've bought the Parity option to a II ci, you can put regular SiMMs in it, but parity for any bank with an 8Bit SiMM in it will be disabled. -- Chuq Von Rospach <+> Editor,OtherRealms <+> Member SFWA/ASFA chuq@apple.com <+> CI$: 73317,635 <+> [This is myself speaking] Trust Mama Nature to remind us just how important things like sci.aquaria's name really is in the scheme of things.
