And all are older than 10 years old. Even MS-DOS came in ROM format for some computers (although I'm not sure if it ran out of ROM, or was copied to RAM before running). >> The Mac OS has never been fully contained in ROM. Starting with the Lisa in 1983 and the original Mac in 1984, Apple used a 64k ROM that contained GUI program routines (the Macintosh ToolKit). These machines still had to boot a floppy which made calls to the ROM. Best, David Greelish Publisher Classic Computing Press www.classiccomputing.com
