Mainly the hard drive, so disk images can be saved and loaded.
Blocked by #13

Allow the ALU to compare registers, to implement CMP operation, and the cmp flag in the microcode inputs to allow conditional jump, etc. more design work needs to be done regarding compare as well, what should be able to be compared, (eg registers, memory values) and where the output should go (register, compare bit)

When the reset phase command is run, it does not reset the counter, the counter only resets in the next phase update. unsure if this is a user interface or emulator bug.

flags register, phase counter, etc

eg add value to memory

I could change do .net core 3 when it comes out (makes it cross platform), add terminal support, just distribute as .exe, no need for updater

The MMU should be added, including thread-based switching of register values, page table, memory mapping, all associated microcode commands to manipulate it. Thread switching based on a master register should control all of this. The memory viewer also should be updated to view pages at a time and threads and which thread each page belongs too. Read/Write flags for the pages as well, page sharing is required. Also, how is writing to the hard drive/peripherals going to be implemented. RAM and ROM seperation so ROMs can be loaded from files.

Desync between the labels and the checkboxes in the microcode command selection pane, checkboxes that are not selected show as being selected and vice versa, while scrolling. Also, when deselecting items that apear to be selected, it selects them in the model, so the model can be the inverse of the gui at times.

None of the ALU operations allow carry in inputs for multi-word calculations, also I don't know what is happening with carry out, overflow, etc. (ie all ALU flags need re-working)

None of the code is tested, and not all of it is commented.

How should it be tested?
Unit tests
Integration tests
Regression testing

I need to look into how to test things in general and in C#
