The 128k ROM on the other hand does provide immediate benefit. FWIW, when I was working on deprecating the old pc machine types, I originally wanted to stop with pc-1.3 (since I was most bugged by the different naming between "pc" and "pc-i44fx" in the help output). I then only put the 1.4 to 1.7 machine types on the deprecation list without anything in mind. Now this became useful for the 128k bios rework... so maybe we should continue deprecating older machine types for other future reworks that we don't envision yet. Thomas
