I need to buy a laptop which supports OS9, as I have a piece of software which doesn't run properly under OS10. I have the disks and licence for OS9 from a previous laptop. Does anyone know any laptops currently available which would support dual booting OS9 and OSX? The Mac OS8 and 9 compatibility matrixdoesn't show any macbooks at all. Alternatively, any suggestions for reputable dealers in second hand machines?
