By the title I mean a built in option rather than a software or hardware add on and saving / loading to regular domestic audio cassette tape.
We should exclude all third party type loaders from this aka "hyperload" or such as it is only aimed at built in options please.
I aware of the Oric offering a selectable 2400 or 300 rate as well as the BBC Micro (possibly Electron too but I cannot confirm that) offering a 1200 and 300 rate. The Amstrad CPC range also offers 1000 or 2000.
Question is as per the title , what other machines offered this choice as a built in option please ?
