DivIDE and Multiface 3Finally got my divIDE up and running, with thanks again to contributors [url=http://www.worldofspectrum.org/forums/showthread.php?p=679210#post679210…
As far as I am aware, the DivIDE and Multiface 3 are not compatable with one another, as they both page the Spectrum ROM out and use their own ROM when you press the button (on either interface).
