Software Guide the Computer with Growth Potential February 1980 Volume 3 Issue 2 NEW: Professional software guide The computer with growth potential The System Three is Cromemco's best selling small business computer. It's easy to see why. Not only is it ideal for the first time computer user. But perhaps more important, it can be expanded into a comprehensive business facility servicing many varied company requirements. Single -user system You can start small. A 64K computer with a megabyte of floppy disc storage costs under £4,000.* Perhaps your initial reason for choosing Cromemco was its flexible database management system-ideal for client records, order processing, sales analysis, inventory control, and many more business uses; or you might have required the full screen word processing system, capable of printing up to 20 original letters an hour; possibly you needed Cobol, Basic or Fortran to develop your own customised packages. Single -user System Three, with 64K memory, 2 discs, terminal and printer. Easy to use Ideal for small businesses. Whatever the reason, you were highly impressed with the ease with which your Will it expand? Multi-user system very first computer application got off the It was then you discovered that the Fortunately, we can readily expand your ground. So you added another. And terminal is the limiting factor, because ofCromemco. Unlike other makers' systems, another. And pretty soon quite a lot of the time taken to input data. If only you all we need to do is add some memory and a company business was running on your could connect a second terminal you ®TU-ART interface, and the multi-user Cromemco. could double your system's workload.. .system is ready to run . with aprinter and up to 7 terminals, each with up to 48K. New operating system Moreover, your terminals can function quite independently of each other. Under Cromemco's new operating system they can be used to update and interrogate the company's database; for correspondence, with the word processing system; for data entry, using the full screen editor; or indeed for running any combination of CP/M software, simultaneously. Up to 72 megabytes We can increase your floppy disc storage to 2 megabytes if necessary. And if that's not enough, we can also add Cromemco's hard discs to provide you with up to an amazing 72 megabytes on-line.

Part of this involved examining the purpose and benefits of employing preservation measures in relation to software, both at the development stage and retrospectively to legacy software. The study built on the JISC-funded ‘Significant Properties of Software’ study2 that produced an excellent introduction and comprehensive framework to software preservation. 2 This is a framework document that assists developer groups and their sponsoring bodies to understand and gauge the benefits or disbenefits of allocating effort to: – ensuring that preservation measures are built into software development processes; – actively preserving legacy software.
