58fc9ac827 Moved the debugger out of m68k 2021-11-01 16:51:45 -07:00
transistor
93c080eae6 Fixed interrupts 
Previously the m68k wasn't masking interrupts with an equal priorty.
I also modified how they work, such that the cpus will check the
controller rather than wait for the notification call

250c0e83d2 Minor fixes 2021-10-29 15:05:41 -07:00
transistor
892f93f053 Added BusPort to more accurately emulate the bus requests of the 68k 
The BusPort is created before the CPU and is passed to it.  It can
have an offset, limit the address sizes, and break up bus request
beyond a certain number of bytes into multiple requests

transistor
492027fa7a Fixed a bug in bit field instruction decode 
We were trying to decode the effective address before fetching the
second instruction word for bitfield instructions, which was causing
it to use the wrong word for the offset:width information, which was
preventing the shell from printing to the screen after boot

transistor
93c9307829 Moved I/O to a separate thread 
but I'm not happy with it, and will likely change it in future,
possibly to use two threads and two sets of channels to pass chars
back and forth
