Re-use of Legacy Computers: a comparative pilot

Legacy PC hardware (typically i386 and i486) can be successfully utilised as thin clients of multi-user Windows NT servers, thereby extending the useful life of older equipment and providing access to up-to-date software which would otherwise require hardware upgrade of each client. Care in the selection of legacy machines (eg for good display quality) helps usability.
Executive Summary
Although not suitable for all software (for instance, applications demanding more than 256 colours, or video) a consistent, easily managed computing environment can be delivered to a wide variety of clients covering the range of CPU power from i386SX to Pentium III and across multiple platforms, including Macintosh and UNIX. The absence of per-concurrent-client licensing presents a massive financial obstacle to using the thin client approach for routine delivery of applications to student-owned computers, however.
By re-using legacy machines as thin clients to equip computer rooms, savings approaching 50% of capital costs (compared to all-new equipment) are potentially obtainable, although high software licensing costs drive down savings. A rolling programme of replacement of equipment is still necessary to maintain the usefulness of computer room facilities - but this can be facilitated by the thin-client approach. As with any multi-user system, high reliability of the server and effective security controls are critical elements for success.
