Chips and Technologies Inc, San Jose, California has what it claims is the first single-chip protocol controller for IBM 3270 terminal emulation, and has also announced a new family of Personal System/2 Micro Channel interface chips. Chipslink, claimed to provide the lowest-cost micro-to-mainframe solution available, is an application-specific integrated circuit that enables 3270 emulation boards to be implemented with just eight chips, reducing the standard component count by 80% to lower board costs. There should also be room for it on most Personalike motherboards. It is claimed to be compatible with all IBM and Digi-tal Communications Associates 3270 IRMA emulation software, including all file transfer applications. It accesses external as well as internal microcode so that designers can program in their own proprietary additional facilities. It can also be used in PS/2 computers with Chips and Technologies’ companion Micro Channel interface part, the 82C574. This new line includes two standard MicroChips: the 82C611 for memory, input-output and multifunction adaptors, and the 82C612 for peripheral control adaptors. No pric-es or delivery dates were given for the new parts.
