Datapoint Corp has unveiled three more 80386-based processors and says it will support the 80386-based IBM PS/2 Model 80 in its ARCnet multi-tasking, multi-processing, multi-user network environment. Joining the existing 80386-based 7900 multiprocessor, the three new computers are the 7700, supporting up to 25 users, the 7800 dual processor, and the 7950 multiprocessor, which will take up to 300 users. The 7950 is described as having a symmetrical multi-processing architecture that optimises throughput in a multi-tasking, multi-processing, multi-user environement. Tasks are pooled and then assigned on a priority basis to the next available processor, rather than being arbitrarily assigned to one of several processor queues to await handling, as in an asymmetrical multi-processor. The 7950 comes with from two to six processors and supports up to 7.7Gb, up to 12 ARCnet local networks, and 128Mb of memory. The dual 7800 supports up to 90 users and 568Mb disk. As for the PS/2-80, Datapoint says its RMS/XA network management system turns the box into a multi-user, multi-tasking host with integral network support, providing multi-tasking and windows; multi-user and network-oriented operation; and easy migration to larger RMS/XA.
