Yes, the screen printer wouldn't work with an EI. It needed full
unbuffered access to video RAM, and it read it off the bus. It didn't
screw anything up as I recall, it worked fine with Level I or II BASIC
but naturally not with Disk BASIC.
Try to imagine what it was like to try getting a program listing from
the damned thing.
