# Dev notes — 2023-08-17

## Goals for today

- [ ] *ADDR - Add relative offsets - `*ADDR +1`, `$ADDR -2`
- [ ] ? Add keypad visualization to simulator
  1. Display qwerty-to-VIP mapping for reference
  2. Highlight the most recent keypress on there
- [ ] Notes re: ROM and/or tape loader

## Program ideas

- Programming ideas:
  - Keypad display
    1. Light pixel corresponding to most recent keypress
    2. Display character corresponging to most recent keypress
  - Draw dot at (x, y)
  - Move dot around display using keypad

## Docs/graphics ideas

From apple note "2023-07-17 - cardiograph - worksheet for hand-assembling code… + other docs"

- [ ] docs/graphics: machine code quick ref (ops + short explanations + mnems)
- [ ] docs/graphics: assembly quick ref (as above, plus assembler-specific syntax like constants)
- [ ] docs/graphics: worksheet for hand-assembling
