Another CPU for the collection of things to nail to an #rc2014 #rcbus system. This time it's an Intel 80196. Quite a fascinating instruction set which basically has 256 bytes of low internal memory that work as registers (somewhat akin to the 8051 but more like the Z8 in that any op works on any register) combined with external memory. However unlike the 8051 it's all sanely mapped into one address space with the registers being the low 256 bytes (with one a zero register and a few are I/O)
