Zenith Data Portable Computer

The ZP-150 was one of the earliest commercially available laptops. It was released in late 1984 by Zenith Data Systems.

The ZP-150 was offered for US$1,995 when bundled with the US$800 Microsoft Works software, but could be found in the Fall 1985 Heathkit catalog for US$1,195. The price came down to US$999 in the Winter 1986 edition of the same catalog and US$699 in the Fall 1987 edition, as it was being phased out with the release of the Z-181 and Z-183. The main target market was the U.S. government and "the mobile executive", for on-site applications. Its relatively small dimensions and light weight allowed it to be easily carried in a standard briefcase or the included carrying case.
