The Zenith Z-89 is based on the Zilog Z80 microprocessor running at 2.048 MHz, and supports the HDOS and CP/M operating systems. The US$2295 Z-89 is integrated in a terminal-like enclosure with a non-detachable keyboard, 12-inch monochrome CRT with a 80x25 character screen, 48 KB RAM, and a 5.25" floppy disk drive.
They were joined in 1921 by Eugene F. McDonald, [4] and Zenith Radio Company was incorporated in 1923. The fledgling company soon became known for its high-quality radios and electronic innovations. Zenith introduced the first portable radio in 1924, [4] [5] the first mass-produced AC radio in 1926, [5] and push-button tuning in 1927. [4]
The Zenith Data Systems Z-19 CRT-display terminal. Zenith Data Systems Corporation (ZDS) was founded in October 1979 following the US$64.5-million acquisition of the Heath Company from Schlumberger Limited by the Zenith Radio Company. [1] [2] The company's initial headquarters were located in Heath's own headquarters in St. Joseph, Michigan.
They are equipped with new SAFOX II autofocus module and power contact to enable power zoom function in power zoom FA lenses. In the United States the series was called PZ, while in the rest of the world it was called Z. Z-10 (1991) Z-1 (flagship model) (1991) Z-20 (1992) Z-50 (1992) Z-1P (flagship model) (1994) Z-5P (1994) Z-70 (1995)

Priced at $75, it was introduced in January 1942 but ceased production in April 1942 as Zenith shifted their production to war-related equipment. During this short production run, some 35,000 units were produced and sales data showed that ...
The Z-100 used a 8086-family microprocessor, (the Intel 8088), but otherwise had a completely different internal architecture from the IBM PC.. At the time Microsoft's MS-DOS was not specifically geared to any specific hardware platform, but could be tailored to run on most any system as long as it used a 8086-compatible microprocessor, a situation completely like with the popular CP/M systems ...
