Colin Calder, former general manager of information technology at the UK’s Automobile Association has founded a new company to focus on open systems products. Based in Farnborough, Hampshire, Enterprise Solutions Ltd’s UK and its European operation are to be headed up by Peter Winder, formerly general manager of Sequent Computer Systems in the UK. A US base in California is being run by Kark Klessig, previously president of Quadratron Systems Inc. The company’s first product is the X400-based Enterprise Mail package, which currently runs under Microsoft Corp’s proprietary Windows 3.0 graphical interface environment, though a character-based Unix version is said to be in the pipeline.
