If I recall, Raytheon Data Systems acquired a line of computers from Packard Bell. RDS had 3 lines of computers: 1. Minicomputer which I think was the 250. 2. PTS 100 - This was a field mode controller with memory mapped terminals that could emulate IBM 3270, and other field-mode terminals. This was used by most airlines in the 1970s. 3. PTS1200. This used the same hardware as the PTS 100, but with additional capability and operating system. I don't recall where the PTS100/1200 architecture was developed, but in an IBM bisynch network it significantly out performed the IBM hardware based controller. By 1980, the PTS line was getting very old, and some decisions to develop a replacement system never panned out. Raytheon sold the division in 1983. -- -- Jerry Feldman <[EMAIL PROTECTED]> Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846
