Hayes Microcomputer Products Inc is only a year or so out of Chapter 11 bankruptcy proceedings, but already it feels fit and well enough to contemplate an acquisition. It is going for fellow modem maker Cardinal Technologies Inc, Lancaster, Pennsylvania, where Microsoft Corp co-founder Paul Allen holds a 75% stake, and Allen’s Vulcan Ventures Inc will end up with a stake in Hayes. No financial details were given. Cardinal’s principal products are consumer modems for the small office-home office market. They are distributed through retail outlets and by direct mail order. The firm also manufactures ISDN adapters. It is planned to close Cardinal’s Lancaster factory and consolidate operations at Hayes facility at its Norcross, Georgia base.
