Quote: "Additionally, the BASIC command set for disc access was improved." Is that true? What are those (dis-)improvements? Dis-improvements are: Some RSX commands like |disc.in are removed. And the bios calls the bootmenu at a hardcoded address in AMSDOS rom, making the cpc+ incompatible with third-party DOS roms. One thing that was actually improved is that the keyboard is scanned during disc io.
