-### #1 - Improve CLI interface
-
-I'm thinking of an interface like this...
-
-    $ ./cpu.js -mc code.bin  
-    $ ./cpu.js code.asm
-    $ ./cpu.js --debug code.asm
-
-Full list of flags I want:
-
-    -d --debug
-    -s --singlestep
-    -p --prettydisplay
-    -mc --machinecode
-
-### #2 - Startup: Execute `JMP $FF`
-
-See [2023-08-24](../notes/2023-08-24--dev-notes.md#cpu-start-up)
-
-... say that there's a 1-byte ROM at $FF.
-
-- `00-19` - display (5x5)
-- `1A   ` - pointer to display memory
-- `1B   ` - keypad: value of latest key pressed
-- `1C   ` - reserved for future use (bank switching flag)
-- `1D   ` - initial IP
-- `1D-FE` - free
-- `FF   ` - ROM (unwriteable) - pointer to initial IP
-
-- store `$1D` at `$FF`
-- make CPU execute `JMP $FF` on startup
-- make ROM unwriteable
-
-More step-by-step:
-
-  - Change memory from a Uint8Array to a regular array,
-    and make every entry { number | { type: 'ROM', value: number }}
-  - Store ROM as an object in machine.config.js
-  - Load ROM data into memory at CPU startup (`startCPU(RAM, ROM)`)

-This is a quick todo list.
-
-For extended commentary, see [issues](issues.md).
-
-## Open
-
-### Todo
-
-- Finish WIP on run-cli arg parsing
-- Pass CYCLE_COUNT as a cli arg
-
-- (cpu) !! Fix overflow flag
-- Add a flag for bank-switching to the ~zero-page
-- Remove run-scripts and add the ability to run `./cpu.js` and `./assembler.js` directly -- cf. [#1](issues.md#1---improve-cli-interface)
-- [fix] (cpu) Make single-stepping work with simulated keypad
-
-### Features
-
-- (cpu) allow arrow keys, too
-- [fix] (cpu) Execute `JMP $FF` on startup / Implement ROM — see [#2](issues.md#2---startup-execute-jmp-ff)
-- (assembler) Validate labels
-- (assembler) Extract debugging to its own module
-- (cpu) Consider adding a VIP-style keypad-based machine code monitor
-- (cpu) Add a mode that prints the display as text, but still animates
-- (cpu) Allow running pre-compiled machine code
-- (cpu) DRY out addition and subtraction
-- [Extended system (secret bonus operations)](../notes/2023-08-07--dev-notes.md)
-- (research) Review CHIP-8

-### Documentation
-
-- Improve docs for flags register
-
-### Testing
-
-- Display (hex) numbers
-- Greater than
-- Minimal LOGO-ish interpreter for turtle graphics
-
-
-## Closed
-
-- 2023-08-26 - [fix] (logging) - 'undefined operand' situation is caused by assembling to an initial IP of $1C, which is an odd number
-- (assembler) Pass asm line thru to cpu to print when debugging
-
-
-## Abandoned
-
-- (assembler) Return pure machine code when printing to stdout (and not in debug mode)
