When the 3A ROMs are used without the transformer, the left side of the image may be wrapped back on itself and the Horizontal Position control doesn't have enough range to fix it.

The regular video configuration works ok with the transformer installed, so once installed you probably won't need to remove it, but it is preferable to adjust the controls on the video board when switching between the video configurations.

That's fantastic! Once I have my Lisa operational, this is getting bumped to the top of my list.

However, with the 3A ROMs you're limited to Macworks... you can't run the Lisa Office System, or Unix :(
