It initially designed and manufactured custom and semi-custom integrated circuits.
In 1987, Appian responded to this demand by developing the POACH (PC-On-A-Chip) peripheral series, one of the first chipsets of its kind, enabling manufacturers of PC AT clones to simplify PC motherboard designs and reduce cost and time to market.
Intel second-sourced to Zymos Corp. of these 82230/82231 High Integration AT-Compatible Chip Set.
ZyMOS was founded in 1978 and changed its name to Appian Technology Inc. on November 1, 1990, just after an acquisition of Renaissance GRX, which was based in Redmond, Washington.
This merger helped to add to Appian's line of advanced VGA boards and software.
