The fall of two milestones11/21/2009
Last week was busy in terms of crucial decision making. If Heritage/1 were a real machine being designed by a real-world manufacturer, last week were be one of hot meetings and heavy memos.
Two milestones was definitely defeated: The division of the Backplane in DATA and CONTROL slot types, and the old idea that the Console must offer static hardware debug capabilities.
The former opens an important opportunity: the possibility of wiring the Console's panels directly to the Backplane via ribbon cables ended with header connectors. So far I simply had no pins left in the Backplane connectors for that so ribbon cables had to connect to a card which is not a clean solution.
The later resolves a tremendous bottleneck that I had with the Console's design since "debug capabilities" turned very complex in implementation. Its removal has lead to accelerate the project in a notable manner. Here is the new Console without hardware debug capabilites:
