GR8BIT

GR8BIT is an educational 8-bit computer hardware and software platform, upon which users can experiment with computer electronics in a simpler computer architecture compared to modern mainstream electronics. It was created by Eugeny Brychkov and licensed by the MSX Licensing Corporation.

History

AGE Labs announced[1] in 2011 the launch of a MSX kit called GR8BIT[2] - the do-it-yourself computer for learning purposes, which was licensed by the MSX Licensing Corporation. The kit is priced at $499 and includes all necessary components to assemble a working MSX2 compatible computer, except for an ATX chassis, power supply, floppy drive, hard disk, PS/2 keyboard and monitor. It also comes with assembly and operational manuals and a supplement compiled from vendor and community support.
