Is it okay to use 9-bit simms? (that's what I have!) Is it necessary to hold any pins hi/lo? I would like to retain the ninth bit in case I move the simms to a PC. Are there any tricks involved in removing/replacing the main board, I remember having to bend the board to get it back when I opened the Mac to have a look. -- Neil Faulks ..!ukc!kcl-cs!neil neil%cs.kcl.ac.uk
