One minor question: from the schematics, it looks like the memory expansion changes the address decoding so that the user port/tape button sense can only be accessed at $FD10, the byte that controls the expansion is at $FD16, and the other bytes in the $FD1x area are "unused" (floating data bus). Is this correct ?
