<p>A computer installation having a modular digital architecture (MDA) comprises a universal base module (UBM) (1) and one or more functional upgrade modules (FUM) (3) detachably connectable to the UBM (1) by a modular upgrade bus (MUB) (2). The MUB (2) comprises a respective bus link within each module (1, 3) such that, when the modules (1, 3) are connected together, the bus links of the modules are connected in series to form the digital MUB which includes sub-buses for supply of power to the modules and transfer of control and data signals therebetween. Such an MDA can be used to produce a wide range of systems using the same basic architecture, such as a network computer (NC), a personal computer (PC) incorporating FUM's providing various PC features, such as an enhanced processor, a CD ROM drive, a hard disk drive, etc., or an appliance computer (AC) incorporating FUM's providing a range of appliance functions for the home, office or classroom, such as an audio system, an interactive television system, an office telephone system, a home security system, etc.. Furthermore the system permits straightforward FUM replacement or upgrade by addition of further FUMs without requiring any particular technical expertise.</p> |
