Plotters and controllers
For two weeks before Christmas, UK architectural practice Hulme Chadwick and Partners moved their design office to the Design Centre. In an exhibition organized by Andrew Chadwick and Nicholas Courts for the Royal Institute of British Architects (head of practice Andrew Chadwick is also chairman o f the RIBA Computer Group) and the Society of Industrial Artists and Designers, the architects went on designing almost as normal while demonstrating to the 600+ visitors how computers can be used in a professional design office. Kit on show ranged from the RIBA 's own TI energy calculator ( £ I 0 0 £500), through a Superbrain micro plus Olympia printer (£2000-£6500) used amongst other things for rudimentary 3D, to the practice's £69 000 CalComp IGS500 drafting system. Hulme Chadwick have been using the two-workstation system for almost two years; it has also formed the basis for their associated bureau, CCD. The CalComp was selected, according to Andrew Chadwick, for the joystick controlled pan and zoom on its raster displays. Also on show was the ]ones Cassidy Mellor thermal analysis program TAS °. Developed at CranfieM Institute of Technology, it runs on a Tektronix work.station connected to a Cranfield minicomputer. TAS ° simulates the thermal behaviour of buildings and produces graphs and tables of daily energy consuption and internal conditions o f any building type. It can examine condensation, cost-effectiveness o f Iow~nergy buildings, passive solar benefits, summer overheating avoidance and establish priorities for energy conservation investment.

Low-cost Appliconsystem
BEASY can solve problems with 'infinite' boundaries, such as underground tunnels or building foundations. It is a modular system; modules currently available cover potential and stress analysis problems, for 2 and 3D and axisymmetric cases. BEASY can be bought, or used on a bureau or consultancy basis.

Applicon are launching two low-cost CAD/CAM systems for small to medium sized firms. The systems include software for either mechanical drafting or printed circuit design. The system hardware comprises a DEC PDP11/34, Applicon's Graphics-32 Display .Processor, 200 Mb disc and an 800/1600 bpi dual density magnetic tape drive. Two graphics workstations may be connected to the system, which can be used for up to three concurrent tasks. The systems also include a TX-38 console printer, and one T-16 monochrome graphics workstation. The systems may be upgraded to the AGS/895, which allows for up to four workstations and eight concurrent tasks. Prices of the systems start from £78 000. (Applicon UK, Regent

Calcomp are launching the Model 953 vector/raster controller, for use with pen and electrostatic plotters. The 953 reads standard Calcomp 921/925 format pen plotter tapes or Calcomp 907 format random vectors input across aynchronous or bisynchronous data lines from a local or remote host computer. The controller performs all necessary vector ordering and vector to raster conversion. Up to 8 plotters can be connected to a single controller. Prices of Model 953 start at around £17 000, depending on tape density and memory capacity. Also being launched are two new plotters, the Model 5500 electrostatic plotter/printer and the 1060 drum plotter. The Model 5500 has a resolution of 200 dots/in and can plot at speeds of up to 57 in2/s (367 cm2/s). The Model 1060 has a 4 ft 6 in wide drum (1.37 m), providing a maximum drawing size of 4 ft 6 in x 10 ft (1.4 m x 3.0 m). The plotters can take four pens, and has a drawing speed of 30 in/s (0.76 m/s). Price is about £26 000. (Calcomp Limited, Cory
