Canada’s Elsid Software Systems Ltd will this week introduce what it calls the first true real-time spreadsheet, running under the X Window System and the Lynx Real-Time Systems Inc’s real-time Unixalike. The company says it redesigned its Ripcam product from the ground up, producing version 2.2 and maximising its performance. Elsid says the new spreadsheet is real-time at every layer from the kernel to the application to the user interface. Elsid says it differs from other similar applications in offering full-duplex real-time communications in both data and control sequences and in both passive and active modes and real-time graphics.
