CPU Emulator

A project log for AYTABTU - Discrete Computer

After the apocalypse we have to build computers from stuff we can make at home, I.E Transistors, diodes and resistors.

It only took me about four hours to whip up an emulator for the CPU using golang and a library called termbox to handle the output to the screen (it's a lightweight version of curses). Since I'm an old C programmer and this is only my second golang application it probably have a lot of ugly C-mannerisms in the code - but it works and can execute the code I fed to it.

I still need to implement some rather important functions like Load code from file and Edit data in the code- and data RAM spaces.

It could also be nice to have a simulated serial port/uart on a tcp socket that can be telnetted to.

And highlighting of fields that have changed during the last executed opcode as well - that would look very professional :-)

So a couple of hours more tonight to finish off the emulator....
