This computer was assembled by Oak Universal Ltd of Bradford, UK and was based on the BBC B+ 64K computer with twin 5.25 inch disk drives.

The Acorn BBC Model B+ was released in 1985. The Model B+ had new features : 64K of RAM instead of 32 KB and internal circuitry for the Econet and Disk Drive as standard (both available as an upgrade in the models A and B). The later models included disk support as standard, using either an 8271 or a 1770 disk controller. There was also a B+ 128KB model (with and extra 4x16KB banks of "Sideways RAM"). The B+ models had 48KB of ROM because they had an extra 16KB with the DFS. It used a MOS 6512A processor, but at the same 2MHz that the A and B models used.

This system, together with additional Watford Electronics 3.5 and 5.25 disk drives were kindly donated by Mike Stapleton.
