Fix bugs discovered by running diagnostics. KI10 will now pass
all DBKEx diagnostics. RP10 and RC10 drives will pass diagnostics
except those involving parity errors and sector counters which are
not implimented.
Added support for KI style interrupts. Added comments to CPU code.
Fixed bug in MUUO under KI. Fixed RH10 to work under KI. Fixed bugs
in handling of record space under TM10 controller. Added type casting
into DF10 code and verified it works correctly under 22 bit operation.
Started adding support for PDP6.
CPU code redone to better use native operations. Start of KI10 support.
Current passes all CPU diagnostics for KA10 and KI10. 22 Bit addressing
support for KI10 now a seperate option.
Major cleanup to code, set_interrupt() now only looks at 3 lower bits
to determine interrupt level. Some Copyright notices have been updated.
DC10 now handles modem control correctly. And will support up to 32 lines.
Modem lines start at a fixed value and follow the data lines.
Update the RP10 disk controller to handle multiple access and
to properly handle status on a per drive basis. Also added in
start of proper debuging functions. Change CPU to not miss
interrupts when multiple interrupts occur.
