# Design Ideas

## Goal

The goal is to create a portable, 8-bit computer from base components, that is at least as functional as an Alphasmart or Freewrite device, and preferrably, has functionality more similar to a Tandy WP-2. Would also be good if the device can improve on some of the design problems of those devices, such as having a positionable screen.

## Architecture

Currently, the best looking architecture to build the computer around looks like the [RC2014](https://rc2014.co.uk/).

This will mean that the computer is a Z80 based system.

## Operating System

Still looking into operating systems. Potential options include CP/M and CollapseOS, but definitely would prefer other options if they exist.

## Serial Terminal

Originally was looking into epaper for a display, but am leaning against it due to issues with slow refresh rates. Instead, looking for LCDs that can be driven by an Arduino that might be able to serve as a full TTL terminal. If that fails, can also use a [diy-VT100](https://www.madresistor.com/diy-vt100/) for the display, and a [USB Host](https://www.hobbytronics.co.uk/usb-host-keyboard) or [E1115 converter](https://www.adafruit.com/product/1136) for keyboard input.

## Case Inspiration

The final product will likely use a 3d printed case, potentially using a modified version of the [HALGRID P-1 Raspberry Pi Laptop Computer Shell](https://www.thingiverse.com/thing:4603966) (itself, based on the [GRID Compass](https://spectrum.ieee.org/image/MzYzMjg3MQ.jpeg)).
