Corollary Inc of Irvine, California, launched a new set of products at the Uniforum show last month, and signed a distribution deal to further its penetration into UK and continental European markets. The company announced that shipments its 386/mp, the longawaited 80386 version of its ATtain 286 add-in multi-processor boards would begin in April. Up to four application processor modules can be added to a 386 machine, each with 1Mb to 4Mb of dual-ported memory and four RS-422 concentrator ports. To each of these, an eight port terminal concentrator can be attached, allowing support for up to 128 users – expanded from the previous limit of 32 users on the 80286 ATtain. Also introduced for both versions was an extended kernel replacement for Santa Cruz Xenix, which handles serial tasks and user input-output, and distributes user activity between up to five processors in a maximum configuration. Corollary says it has around 100 users for the 286 boards, but admitted that interest in 80386 configurations had eaten into its share of the market. It has now introduced a cheaper entry level option with a 32-port halfcard, the eight by four multiplexer input-output subsystem for 386 machines; this includes an 80188 processor, 64Kb memory and four RS-422 ports that will each support an eight port intelligent terminal concentrator. Corollary is pitching this against the existing eight- and 16-port serial cards out on the market. Exclusive European distribution of the product range will be handled by the UK company Specialix Systems Ltd, based in London, which also distributes Chase multi-user input-output controllers. Single quantity, end-user price for the 386/mp is $2,795 for the 1Mb version, $4,195 for the 4Mb version. Free to current users, the extended kernel costs $195, and eight port terminal concentrators are $595. A basic eight-user eight by four multiplexer kit, including the board, concentrator, operating system and cabling, is $1,195.
