| The Enterprise 128 was an 8-bit home computer released in 1985 by British company Intelligent Software and Enterprise Computers Ltd. It was a more advanced version of the earlier Enterprise 64, sharing the same architecture but equipped with 128 KB of RAM instead of 64 KB. At its core, the Enterprise 128 used a Zilog Z80A CPU running at 4 MHz. It featured two custom chips: “Nick” for video and graphics processing, and “Dave” for sound and memory management. The graphics capabilities were notable, offering multiple video modes with resolutions up to 672×512 pixels (in interlaced mode) and a palette of 256 colors, although fewer could be displayed simultaneously depending on mode. The sound system used three channels of programmable sound, based on the General Instrument AY-3-8910 chip, with added enhancements. The computer also supported hardware sprites, smooth scrolling, and multiple display pages. An unusual feature was its built-in EXOS operating system and a BASIC interpreter stored in ROM. The EXOS environment was modular and allowed device and language extensions to be loaded via cartridges or external drives. Storage options included cassette tape, but the Enterprise 128 could also be connected to floppy disk drives and other peripherals via the expansion ports. It had a distinctive case with a full-size keyboard and a joystick mounted on the right-hand side. Despite its advanced hardware and innovative features, the Enterprise 128 was not a commercial success, partly due to production delays and a crowded market. However, it remains well-regarded by enthusiasts for its technical capabilities and forward-thinking design. |
