Quote from the article we are commenting on...
"Everything you set up to customize the system, like desktop icons, window positions, desktop resolution, and other settings is reset every boot unless you manually tell the system to save the current state as the "boot file.""
OS in ROM so of course no state could be saved except as a file on a floppy disk. ROM based systems have certain advantages when working with classes of investigative and curious teenagers.
Hard drives came a bit later; there was a retrofit of a Rodime 20 Mb drive that fitted into one of the podules on the back of the A310, and had its drivers in an updated system ROM. Good times.
Most of the hardware had rom with its drivers in it. Meant just about everything was a plug and play experience.
And it is true that bit was fast, but once you'd customised the font and replaced all the system icons and set strongedit as your default editor in your!boot, it could take quite a long time to start up.
