+ Kawasaki LSI
+ KL5C80A12 CPU (KL5C80A12CFP on hng64.c)
+
+ Binary compatible with Z80, significantly faster opcode timings, operating at up to 10Mhz
+ Timers / Counters, Parrallel / Serial ports/ MMU, Interrupt Controller
+
+ (is this different enough to need it's own core?)
+ (todo: everything, some code currently lives in machine/hng64_net.c but not much)
