Quote: Video memory could be a hidden factor. 40 bits virtual memory is more memory than all the C-64's ever sold. Ben. That is an interesting statistic. What else is amazing is how much could be done with a 1MHz processor and 64kB of RAM. I have now set the swap space set to ‘Windows manages’. I thought I had it set that way, but when I checked it was set to 6GB. For some reason I am reminded of the time I recommended a 4MB RAM board be purchased for a 286 machine. All the apps the user needed to have running just would not work with the machine’s original RAM. The additional RAM was on a PCAT card not the motherboard. |

It makes one wonder where we are going with all this computing horsepower. Artificial realities just around the corner. |

After letting this project sit for a few months, I went back and reviewed it and found a bug in the processor. Absolute address branches were not sign extending the address as they should be. I was amazed this was not hit as an issue when running software, but all the code must be using relative addressing which was correct. |
