Masscomp, Massachusetts Computer, seems to be collecting a remarkable number of different SNA implementations for its multi-68020-based engineering systems, and has now gone to Morning Star Technologies for SNA 3270 and SNA 3770 software emulations for its MC5000 family. The programs enable Masscomp users to communicate with an IBM mainframe in an SNA network. The Morning Star products provide emulation of the 3274 cluster controller, providing support for up to 32 attached devices that can fool the host into thinking they are SNA devices. Each device can be configured either as a 3287 Model 2 printer, or a 3278 Model 2 display terminal. Morning Star’s SNA 3770 package emulates the antique IBM 3776 Model 3 communications terminal as a Remote Job Entry terminal. Horizon series communications boards will support multiple protocols simultaneously. A Masscomp computer can now run both 3270 and 3770 together, or either with X25 or HASP. The complete package is $5,795. The Horizon 800 series communications board can be had from Masscomp but for the SNA 3270 and 3770 software, users have to go to Morning Star. Single-unit end-user pricing starts at $2,795 for the Horizon 800 and at $2,995 for the SNA 3270 or 3770 software.
