Protogate Teams with Stromasys to Provide Solutions for Existing Customers with DEC and Simpact Hardware and Software

- A DEC VAX VMS system using Simpact ICP boards can now be replaced with a PC and Freeway server with minimal software changes -

SAN DIEGO, California, 1 March, 2017 -- Protogate Inc. has teamed with Stromasys to provide easier replacement solutions for customers who are running VMS applications on older DEC hardware and interfacing with Simpact ICP boards on Q-bus, VME, or VAXBI based systems.

Stromasys provides a software product called CHARON-VAX that runs on a Windows or Linux PC. The CHARON-VAX software emulates the low-level interface to several DEC VAX and Alpha systems. This allows a customer to run a copy of a VMS disk image on a newer PC rather than on the existing VAX hardware.

Protogate provides its Freeway server product with PCI-based ICP2432B communication boards. The Freeway/ICP2432 combination is the network-based replacement for the existing Simpact ICP products (for example: ICP1622, ICP3222, ICP3232, and ICP6000).

Protogate also provides a software product called SQIO. The SQIO software is designed to read packets from the VMS application program in the "old" ICP format, convert them to the new DLI format, and send the packets to the Freeway. It does the reverse conversion for packets coming from the Freeway. The function calls to the SQIO software are designed to be as similar as possible to the original Simpact device driver calls. This minimizes the software changes to the original VMS application program.

The following diagrams show examples of a typical VAX hardware and software replacement using the Stromasys and Protogate products:
