In 1983 Tycom Corporation introduced the Tycom Microframe, heralded at the time as the "first fourth-generation computer".
The computer at the core was an Intel Corp. 8088-based multiuser system that had a performance range extending from a mid-range microcomputer to a high-end minicomputer of the time.
Described by some observers of the London computer scene as "future proof," Microframe contained a vendor-developed bus architecture called Versatile Base Bus Connect (VBC) that enabled its chassis, which was available in 6-, 12- and 22-slot versions, to accommodate Zilog Z80, Motorola 68000 and Digital Equipment Corp. PDP-11/70 board-level upgrades. The main Intel 8088 processor ran Microsoft MS-DOS, and the hosted CPU boards allowed the system to run other operating systems including CP/M (on the Z80) and Xenix (on the 68000 board).
