  • How can I tell if 128k in codeIs there an easy way in code to check if the Spectrum has 128k, rather than 48k so I can display a message "Must have 128k" etc

    It's also worth noting that the paging test will "fail" if a 128k has been put into 48k mode by using the menu or the SPECTRUM command. The test will "pass" (yay, we have 128k) if the 128k machine has been put into "USR0" mode.
