a56f1cfde1 The 8080 CPU goes through the Bus interfaces for all memory accesses now. The PCjs CPU maintained its own copy of Bus memory structures and interfaces, partly for improved performance but also because some CPUs can turn on address translation (ie, paging), making separate interfaces a necessity. However, PC8080 has much lower performance requirements and no address translation requirements, so we should revert to the original Bus interfaces. 2016-05-02 12:54:55 -07:00
