+# For MVP functionality
+
+- `drive` component
+- volatile filesystem
+- volatile drive
+- device info
+
+# To re-evaluate
+
+- The current system has the computer store the components and the component *types* store the state. Perhaps the ComponentType struct should be renamed
+to ComponentState.
+- More stack manipulation functions to allow libraries to have more APIs.
+- Having a copy of the context stored directly in requests instead of having to use getComputerContext, as it simplifies the APIs and allows them
+to be made more portable.
+- Exposing more context wrappers than just the memory allocation functions.
+- Exposing more internal functions that may be useful to the user to prevent pointless rewriting and duplicate machine code.
+
+# Vanilla components needed
+
+Not everything OC has (as a few of them are really MC-centered) but most of it.
+
+- `data` component (note: maybe add hamming code support?)
+- `modem` component
+- `tunnel` component
+- `relay` component (note: OCDoc still refers to it as `access_point`)
+- `computer` component
+- `geolyzer` component
+- `net_splitter` component
+- `redstone` component
+- `motion_sensor` component
+- `printer3d` component (note: maybe add signal for when printer completes?)
+- `sign` component
+- `microcontroller` component
+- `hologram` component
+- `disk_drive` component
+- `note_block` component
+
+# Custom components needed
+
+- `oled` component (OLED screen, a store of draw commands and resolution from NN's perspective)
+- `ipu` component, an Image Processing Unit. Can bind with `oled`s, and issues said draw commands
+- `vt`, a combination of a GPU, a screen and a keyboard with limited functionality. Offers direct operations on the video memory
+- (maybe) `qpu` component, a Quantum Processing Unit for quantum computing
+- `radio_controller` and `radio_tower` components, for radio telecommunications
+- (maybe) `clock` component for arbitrary precision time-keeping
+- `led` component for LED matrixes and/or LED lights
+- `speaker` component, allows playing audio by asking for binary samples and pushing a signal when it needs more
+- `microphone` component, allows reading audio from nearby sources
+- `tape_drive` component, compatible with Computronics
+- `cd_reader` and `cd_writer` components, to work with CDs
+- `serial` component, for serial communications with other devices (USB?)
+- `iron_noteblock` component
+- `colorful_lamp` component
+
+# To make it good
+
+- make more stuff const if it can be. Gotta help out the optimizer
+- write a bunch of unit tests to ensure the public API works correctly
+- ensure OOMs are recoverable
+- do a hude audit for bugs at some point
+
+# To make it fast
+
+NOTE: we're mostly bottlenecked by the architecture (typically a Lua VM) and the intentional bottlenecking from call costs.
+
+- make signals use a circular buffer instead of a simple array
+- use a hashmap for components (and device info), this may require reworking how iterating over them is handled
