Project Beta (AKA Dragon 128) was something altogether different, and saw GEC Dragon really wanting to hit the big time. Expecting to retail at £2500-3000, the micro housed twin 68B09 processors, had 256K RAM (expandable to 768K) and offered two internal 3.5" floppy drives with an external hard disc available as an add-on. Together with an on-board power supply the machine also incorporated an 80-column display and an RGB monitor connection

The main CPU unit had a flat-top to support a monitor and the detached keyboard also featured a separate numeric pad. Together with a parallel Centronics, RS232, light-pen and mouse port, a mother-card was supplied providing expansion boards to be fitted. At the time of announcement only three had been fully developed
