Band indicative segmented tuning bar display

A tuning system for a television receiver produces a tuning bar for display on a display screen. The horizontal position of the tuning bar is controlled in response to the tuning voltage. The tuning bar is segmented into a large portion and one or more smaller portions. The number of smaller portions of the tuning bar is representative of the band being tuned.

The term televison receiver as used herein includes television receivers having a display device (commonly known as television sets) and television receivers without a display device, such as videocassette recorders (VCR's). Many modern television receivers include circuitry for generating an on-screen indication useful for tuning the televison receiver to selected channels.

In medium-priced and higher-priced television receivers, it is common to include an alphanumeric on-screen display (OSD) generator circuit for providing an on-screen display of channel number. However, in lower-priced television receivers, the use of a separate OSD circuit is generally precluded due to cost considerations.

It is known in lower-cost televison receivers to use a vertical tuning bar to display tuning information. In such a system the relative horizontal portion of the vertical tuning bar is indicative of channel number. The horizontal displacement of the tuning bar is generally a function of magnitude of the tuning voltage required to tune each channel. Band information (VHF-low VHF-high, UHF in the United States, or Bands I, II, III and UHF in Europe) is usually indicated by the color of the tuning bar. Such a system as described thusfar is known from U.S. Pat. No. 4,410,913 (Chin et al.) issued 18 Oct. 1983.

TMS1000

General

General Information
Texas Instruments was locked in a race with Intel to create the first microprocessor. By most accounts Intel won with the 4004, but there are a few die hard TI fans who say the TMS1000 was first, because it was the first “computer on a chip” and that the 4004 was just a calculator chip.

Texas Instruments followed the Intel 8080 with the 4-bit TMS1000. So, while Intel was leading the industry in microprocessors, TI led with this industry unique design "a computer on a chip", specifically designed for control and automation purposes. The 1000 was the first MCU (MicroComputer Unit) , which is an MPU (MicroProcessor Unit) with other support chips (such as RAM, ROM, counters, timers, I/O interfaces) integrated on to the same silicon chip.

The original 1000 family consists of 6 chips the TMS1000 and TMS1200 are basic chips, the TMS1070 and TMS1270 are high voltage versions to interface to displays, the TMS1100 and TMS1300 provide twice the on-board ROM and RAM. The TMS1000, TMS1070, and TMS1100 are 28-lead packages, the TMS1200, TMS1270, and TMS1300 are 40-lead versions of the same chips (just 200 to the 28-lead chip numbers).

In the 80's TI added to the 1000 family. The 28-lead TMS1170 started with a TMS1100 base and added fluorescent display drive capability and expanded memory (2KB ROM). The TMS1370 was the same as the TMS1170 and added 27 I/O lines. An expanded memory group based on the original TMS1000 chips was also created. They were the TMS1400, TMS1470, and TMS1700 (64 Bytes RAM, 4KB ROM). There were 40-lead versions of the TMS1400 and TMS1470, which because the TMS1600 and TMS1670. CMOS versions were also added, denoted with a "C" suffix, such as TMS1200C.

The TMS1000 also had system evaluator chips. The original evaluator chips were the TMS1098 and TMS1099. These 64-lead evaluator chips were ROM-less versions of their corresponding standard chips. The TMS1099 supported the TMS1000/TMS1200 and the TMS1070/1270. The TMS1098 supported the TMS1100/1300. Later evaluators were introduced to support the entire TMS1000 family, they were the SE1000P (supports TMS1000,1070,1200,1700), SE2200P (supports TMS1100,1170,1300,1370), and the SE1400P (supports 1400, 1470, 1600, 1670).

The success of the the TMS1000 is demonstrated by its long lifecycle (over 20 years) and its expanded product line. The TMS1000 is found in many appliances, control systems, and games. Most of these chips were sourced by companies for direct use in their products and will have custom or house numbers on the chips (not the standard numbers listed above). Even TI used custom numbers in its products. The TMS1000 was used as a customized chip in the Texas Instruments "Speak and Spell" educational toy line (See Pictures at bottom).
