The 10-year old Danish company SuperUsers A/S, which has its headquarters in a 16th century castle overlooking the sea north of Copenhagen, is carving out a niche for itself as a Unix knowledge house for Scandinavian and other European countries. The company, now employing 15 staff, is run by Unix guru Brian Eberhardt, and concentrates on training, product development and consultancy. Its own products include custom systems for the likes of the Danish Girobank (in conjunction with Control Data Corp, also very active in Denmark), and X Window System monitoring and debugging tools, such as XSpy. It also provides a channel to supply and support international products for the Danish marketplace – on the books at the moment are the UIM/X graphical user interface builder from Teleuse, VisionWare Inc’s XVision, Glockenspiel Ltd’s C++ range and CodeCenter/ObjectCenter from Centerline Inc. SuperUsers recently collaborated with Uniras to interface its graphics software with UIM/X. The company works with multiple hardware systems, including Sparc, Digital Equipment Corp, Hewlett-Packard Co, Intel Corp iAPX-86 and Control Data – it is about to take possession of a dual processor 4680 CDC machine – alongside X-terminals from Network Computing Devices Inc, Tektronix Inc and Tandberg Data A/S.
