No, there is no such thing as a QBUS map. Q18 systems are like 18 bit Unibus systems such
as the 11/45: they have a max of 124 kW of memory so 18 bits address all available
memory.

as well)
Goodness, never thought of that. Hmmm.. it's probably enough hassle to mod
the software (who ever heard of a 'QBUS map' on a QBUS -11 - but you'd need
it to give DMA devices access to high memory) ...
