Digital Equipment Corp’s contribution to commerce on the Internet is the TP Internet Server software, which it says offers secure business-to-business transaction processing over Internet connections. Aimed at financial services, insurance claims processing, order processing, inventory control and distribution, the software integrates the high-volume, three-tier ACMSxp transaction processing monitor with AltaVista Tunnel encryption and will be available for Digital Unix and Windows NT servers (not OpenVMS, so DEC suggests users of that exploit the affinity between Windows NT and OpenVMS) and will support Windows95 and Windows NT clients. TP Internet Server will be available next month at $6,400 for Windows NT servers and $14,200 for Digital Unix systems. Client software is from $192.
