@mos_8502 @NoelsRetroLab @msh I’m probably spoilt because I’ve been looking at the Enterprise design. It can put any 16k memory block into any bank. And video gets a dedicated 64k block.
In contrast the Amstrads available options are very limited. Also, the restriction to having video in the base 64k. And the system (effectively) also has to go in the base 64k.
Enterprise designed this in from the start. The Amstrad came later but didn’t even consider it.
