Fixed aux memory writes that should have been ignored
...
This was killing the Prodos basic intepreter bootstrapper since a write was
going to main memory at $800, leading to invalid code when the JMP to $0800
from the prodos reloader was done.

6f19957ee7
Added aux memory and 80 column card stubs ...
...
... just enough to fool prodos that there's only 64k of RAM and no
80 column card.

f1dff51564
Added bank switched upper memory

...
With this, DOS3.3 is booting

f8ca059f18
Split IO into its own module
2018-05-09 21:25:21 +01:00
d89c7babf0
Refactored memory read/write to MMU
...
This required moving some common things in a new package to resolve a circular
dependency between cpu <=> mmu.

c2a9e819b1
Made state global, to simplify later refactors

Added keyboard controller

9c9f826c6a
Replaced MemoryMap with an PageTable array
...
There was no good reason to be using a map when an array lookup would have
done nicely.
2018-05-09 10:36:17 +01:00
5d1c25a724
Added MMU and WIP rudimentary apple //e boot test
...
Basic memory management has been implemented since $c100-$cfff needs flipping
with soft switches during Apple //e boot. All memory reads & writes now go
through the MMU. Memory is also dynamically allocated and associated with the
CPU state.
