PJRC forum member Jean-Marc, is it it once again, this time with the tiny, Teensy 4.1-based, T-COMPUTER.

Jean-Marc is the creator of the Atari ST Emulator and MAME Arcade Machine Emulator. His latest project, The T-COMPUTER is a full-featured handheld computing platform, with 42 keys (including D-pad and buttons for gaming) and a built-in 320×240 TFT display. While its small size makes it ideal for on-the-go use, VGA and 16-bit stereo DAC outputs, as well as USB host input for keyboard/mouse/etc., as and a DB9 Atari-style joystick input, make for a great desktop experience as well. As always with Jean-Marc’s projects, the schematic, source, BOM, assembly instructions, and more can be found on GitHub. A detailed demo of the computer’s capabilities can be enjoyed below.
