Shown here is SpeedScript 128, a word processor. The 8563 Video Display Controller (VDC) was an integrated circuit produced by MOS Technology. It was used in the Commodore 128 (C128) computer to generate an 80-column (640 × 200 pixel) RGB video display, running alongside a VIC-II which supported Commodore 64-compatible graphics.
MOS 6569R3 (PAL version) on a C64 main board. The VIC-II (Video Interface Chip II), specifically known as the MOS Technology 6567/6566/8562/8564 (NTSC versions), 6569/8565/8566 (), is the microchip tasked with generating Y/C video signals (combined to composite video in the RF modulator) and DRAM refresh signals in the Commodore 64 and Commodore 128 home computers.
A convenient feature of Commodore's ROM-resident BASIC interpreter and KERNAL was the full-screen editor. [3] [4] Although Commodore keyboards only have two cursor keys which reversed direction when the shift key was held, the screen editor allowed users to enter direct commands or to input and edit program lines from anywhere on the screen.
The system was an extension of Commodore's BASIC 7.0 for the Commodore 128 computer. BASIC 8.0 provided commands lacking in BASIC 7.0 to generate (color) graphics in the C128's high-resolution 80-column mode (640×200 pixels ) for RGB monitors.
GEOS (Graphic Environment Operating System) is a discontinued operating system from Berkeley Softworks (later GeoWorks).Originally designed for the Commodore 64 with its version being released in 1986, enhanced versions of GEOS later became available in 1987 for the Commodore 128 and in 1988 for the Apple II.
The DoubleFloats [30] package provides support for double-double computations for the Julia programming language. The doubledouble.py [31] library enables double-double computations in Python. [citation needed] Mathematica supports IEEE quad-precision numbers: 128-bit floating-point values (Real128), and 256-bit complex values (Complex256).

The Enterprise has a 4 megahertz (MHz) Z80 Central processing unit (CPU), [4] 64 KB (65,536 bytes) or 128 KB of RAM, and 32 KB (32,768 bytes) of internal read-only memory (ROM) that contains the EXOS operating system and a screen editor / word processor. The BASIC programming language was supplied on a 16 KB ROM module.
