ZyMOS Corp, based in Sunnyvale, California says it is in production of its version of the single chip dual serial-parallel port for personal computers where an interface to peripherals such as printers, plotters, colour slide makers, fax machines and telecommunications such as stock quotations and other financial services, and links to other computers are required: the Zy16C452 is fully compatible with VLSI Technology Inc’s VL16C452, said by ZyMOS to have been remarkably successful in a market expected to be worth $40m a year by 1992; ZyMOS did not provide any prices. Mannesmann Tally UK Ltd is going after the business and education markets with its new matrix printer priced at UKP150: designed for workloads of up to 2,000 pages per month, the MT81 80-column machine prints 130chps at 10 characters per inch and has a paper parking facility, which enables users to switch from fanfold to cut sheet stationery without having to manually re-load the tractor feed mechanism; the printer emulates the Epson FX 85 or the IBM Proprinter and has an optional Serial RS232 interface, which allows users to link it to IBM and to other micro systems.
