Working hard on the Simulator

7/8/2010

This simulator written in Turbo Pascal 3.0 proven easier than expected. In only six days (or nights...) of development it got to Fetch and Execute "real code" previously read into "memory" from a hex file.

I wanted it to look primitive, even more primitive than those programs that I used to write with Turbo Pascal twenty years ago. The text-only interface resembles the computer's console in a direct way, no fancy debugging commands have been added other than the ability to read a hex file from disk.


This primitive design has resulted in an intimate experience, very close to the machine being emulated which Console is expected to look more or less like this:


This program does not mimic the Heritage/1 exact circuits but only its behaviour. Hower, it resembles the hardware architecture at the block level, implementing in software the same solutions as in hardware. This match between software and hardware is giving me the oportunity to test those solutions on cold... which wasn't my initial intention, I have to confes...
