From the project
A Motorola 68000-based single board computer designed to run EmuTOS.
This board is designed to run the EmuTOS operating system. EmuTOS is an open-source variant of the Atari ST TOS operating system.
BITSY Mark I is part of system containing this board, a XOSERA_RCBUS board for VGA output, a KEMOJO board for PS/2 keyboard and mouse input, and an RCBus backplane board such as an SC147. Together, this system can run full GUI EmuTOS with 640x240 graphics in 16 colors.
