In July 1977, BCL contracted Allied Business Systems Ltd (ABS) to manufacture the Molecular Mk IV. This also gave BCL access to an ABS machine which was referred to (by BCL) as the Molecular 80. There was a plan that the Molecular 80 would support a new high-level language.
To my knowledge, the Molecular 80 was ever developed, let alone sold by BCL.
(Around the same time BCL contracted with Diablo Systems Inc (part of Xerox Corp) to sell their range of micro-computers. I suspect the availability of those machines meant the Molecular 80 was no longer useful to BCL.)
