Only requirement is ECS Agnus because ECS Agnus always see trap door in usual upper half of 1M chip RAM address space ($80000-$fffff).
Only hardware difference between 0.5M+0.5M compared to "real" 1M chip config is address space where CPU sees the memory: $c00000 or $80000. Agnus' view of address space does not change. (There is even one demo that uses this trick)
This is yet another less known hardware feature. |
Even on ECS you can have "1mb" on chip mem?
