Science fiction predicts that one day, we will carry high-power microcomputers with us. Although smart phones are good, these predictions are more based on cuter systems and closer to existing computers, keyboards and screens. [Jean Marc Harringt] has built something along these routes, which is called T-COMPUTER.
This build revolves around the powerful Teensy 4.1. This means that it has an 800 MHz Cortex-M7 processor, 1 MB RAM, and 8 MB flash memory, which exceeds the specifications of many retro computers last year. [Jean Marc Harringt] paired Teensy with a 42 key keyboard and TFT screen to create a compact handheld computer platform. It is also equipped with VGA, which can be displayed on a larger screen, USB and an old-fashioned Atari joystick port! The power supply is provided by a small rechargeable lithium battery on the back, and 16 bit stereo audio is provided by a standard 3.5mm jack. If you need some interfaces with, you can also use some GPIO.
It can imitate Commodore 64 and Super Nintendo, as well as more covert systems, such as Atari Lynx. Before you ask — yes, it can run DOM. This is an interesting little platform and will be a pleasant retro game and hacker in mobile. If you want to build your own system, you can find files on Github to recreate the system.
Handheld computers are always becoming more and more popular because they can have so much computing power in a small development board format. If you have built your own neat little rig, be sure to let us know! Video after break.
