Boston Business Computing Ltd, the Andover, Massachusetts company best known for extending the look and feel of the DEC VAX/VMS user interface to alien environments, has now pulled the trick for IBM’s RS/6000 Unix machines, offering its VCL and EDT-plus command language and editor for the RISC machine. The new version is $1,000 to $4,000 depending on the size of the RS/6000 and the company looks for them to generate $2m of business over the next two years, Computer Systems News reports. There are already versions for DEC’s own Ultrix machines, for MS-DOS micros, and for Hewlett-Packard and Sun Microsystems Inc Unix.
