The Akai VS-2 was the first VCR with an on-screen display, originally named the Interactive Monitor System. By displaying the information directly on the television screen, this innovation eliminated the need for the user to be physically near the VCR to program recording, read the tape counter, or perform other common features.
Block diagram of a NEC μPD7220 graphics display controller. A video display controller (VDC), also called a display engine or display interface, is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system.
Some electronics simulators integrate a schematic editor, a simulation engine, and an on-screen waveform display (see Figure 1), allowing designers to rapidly modify a simulated circuit and see what effect the changes have on the output. They also typically contain extensive model and device libraries.
The display driver may itself be an application-specific microcontroller and may incorporate RAM, Flash memory, EEPROM and/or ROM. Fixed ROM may contain firmware and display fonts. A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)
So, if this scrolling process involves a full screen Mode 2 or Mode 4 text display (rather worst case) and uses the entire 4K capability of ANTIC's automatic screen memory addressing, then the horizontal scrolling can continue in this manner for about 3,000 steps; equivalent to 75 full screens.
The lead indication for IC 100 is obesity with metabolic complications, and for VAR 200, focal segmental glomerulosclerosis (FSGS). Each therapeutic area offers a “pipeline within a product,” with potential for numerous indications. The total accessible market is over $100 billion.

The Victor 3900 is the first electronic calculator to have been built entirely of integrated circuits (ICs). [1] [2] For its era, the 3900 is extremely advanced; it has a 4-inch (100 mm) cathode ray tube screen to produce a 5-line display, has separate memory for storing three intermediate results, supports numerical rounding, and is still "smaller than a typewriter".
In theory, the "graphics" screen text was drawn on could be the text-mode semigraphics screen for a more standard (for the time) 56x26 or 56x39 high-resolution text mode, though in practice this real text mode was apparently never used (if it even could be). 4 of 8: Kaypro II series: 1982: 2 KB: 80×24 Mono, on 9" built in CRT Semi: Presumably ...
