+# Dev notes — 2023-08-28
+
+Two current goals:
+
+## 1. Implement a new CLI interface
+
+- New arg-parser
+- Allow setting clock speed with a command line flag
+
+
+## 2. Re-architect
+
+- Move the bulk of cpu.js to cpu.lib.js
+- Add a way to register functions to be called each cycle
+- Create a new 'cardiograph.js'
+    - imports cpu.lib.js
+    - registers functions for logging, updating display
+        - (split those apart)
+    - provides terminal interface
+        - get machine code input from stdin (or like, file stream?)
+        - `./assembler.js | ./cardiograph.js 
+        - see below re: changes to assembler
+- Assembler
+    - Move CLI interface into assembler.js and delete run-assembler.js
+    - Add a --json flag, which causes the assembler to print the json of {machineCode, debugInfo} on stdin
+    - Otherwise, print hex/bin to stdin
