Uniscope

Uniscope was a registered trade mark for a set of Sperry Univac dumb terminal products. The trademark was applied for October 13, 1969. Several models were produced: the Uniscope 300, Uniscope 100, Uniscope 200, the UTS 400, the UTS 10, the UTS 20, the UTS 30, the UTS 40 and the color UTS 60. There was also the UTS 4000 cluster controller and terminal line, and the SVT-1120. Various models supported 16x64, 12x80, and 24x80 display formats. The UTS 4000 line had a COBOL compiler available that made it possible to do local processing in the cluster controller, and the UTS 60 was also capable of being programmed. This line of terminals roughly paralleled the similar IBM product, the IBM 3270.

A proprietary communications protocol was common to all members of the Uniscope product line. Groups of terminals were generally dropped off a common communications line via a multiplexer (mux) and identified by remote identifier and station identifier symbols. Some terminals may have been equipped with peripheral devices such as printers and recording devices (cartridge tape or floppy disk) which were identified on the communications line by a device identifier. Terminals on a drop were sequentially polled for traffic, sometimes with a general poll to which any terminal with traffic could respond. A fairly complex data presentation protocol permitted application programmers to format a screen for any number of business purposes. For example, fields could be described that would accept only numeric or alpha-numeric characters. Some fields could not be changed by the terminal operator. A protocol extension permitted programmers to specify color for each field and lines on the borders of each cell (underline, or vertical bars, etc.) The Uniscope display protocol, while proprietary, roughly parallel the ANSI X3.64 standard.

The color UTS 60 terminal using two Motorola processors arrived on the market at about the same time as desktop computers with EGA monitors. The general consensus was that the UTS60 was over-engineered and overpriced for the emerging market. Eventually emulation software for the Uniscope line running on desktop computers ended manufacturing of the genuine article. Screen size of the original Uniscope 100 was 12 X 80 or 16 x 64 characters. All letters were in capital. Each character was individually drawn as a series of splines using technology developed for displays in military cockpits. Later Uniscopes supported a 24 X 80 screen using raster technology, and upper and lower case characters. There were versions that had the various national code sets for different European countries to enable pound signs, and various accented characters, etc. There were also versions that had Katakana code sets for Japanese.

Unisys developed the INFOConnect terminal emulators for PCs that included use of the Uniscope protocols in the early 1990s. There continue to be vendors that sell terminal emulators for these machines.

The Uniscopes were Sperry Univac dumb terminal, devices with a keyboard and display to allow a person to interact with a Univac mainframe computer. Several models were produced: the Uniscope 100, Uniscope 200 were hardwired terminals with fixed functionality. The UTS 10, UTS 20, UTS 30, UTS 40 and the color UTS 60 were "intelligent terminals" powered by 8-bit microprocessors, predecessor of today's powerful chips that run today's PCs. The UTS-400-TE was specialized terminal that had a powerful text editing program burned into firmware intended at first to allow for the editing of simple copy such as that for a newspaper, and later adapted as a prototype word processor with 8" floppy disks and driving Letter Quality daisy wheel printers.
