RE: Examples of Memory MAP with 2x Clonix-D?
Some clarifications ...

In general, ROM page options are: fixed, port-lower-page or port-upper-page
(there are other options, but for our discussion here, these are the one we are using)
so there is no dynamic page filling here, code run from ROM which has fixed addresses.

All the hardware connected to the system bus receive the same cpu signals at the same time,
which include the motherboard and all connected peripherals/modules.

Generally, a bus lock-up happens (41 freeze) when two ROM share the same address/bank.
Some emulation devices, like Clonix/NoV modules, detect that scenario and disable its own ROM for the faulty page if it can.

Some devices like HePaX are able to change their ROM address(es), but that is a device capability and not an orchestrated feature of the 41OS.
