# Dev notes — 2023-08-29

## Short-term goals:

- [ ] **Update main TODO list**

- [x] Move notes, issues to their own branches
- [x] Make worktrees for those branches

- [ ] split into card, io, graph, all bound together in cardiograph.js  
  → have split it a bit... display and keypad are both in `io.js`

- [x] make CPU errors throw errors

- [ ] new CLI interface
  - [x] replace `run-...` with `./assembler.js` and `./cardiograph.js`  
    → have done a basic implementation, which is a regression of the feature set
  - [ ] parse args in a safer way
  - [ ] implement missing features

***

- [ ] **fix overflow flag**
- [ ] implement 'jmp ($FF)' on startup
  - [ ] implement ROM

- [ ] re-implement single-stepping
