In 1977, Martin Research's vice president of marketing Kerry Berland had professed that the "ultimate market" for personal computers would "be a packaged, high-volume, low-cost consumer product", and that while his company would "like some of that market ... we have serious doubts that anyone who doesn't control the semiconductor process will make it there." In

Around the turn of the 1980s, the company pivoted toward the business, industrial, and medical markets. In the process it discontinued its kit computers, changed its name to Qwint
Research, and moved its headquarters down the road from its original Commercial Avenue location in Northbrook. Instead of

The 8008-based Mike 1 was short-lived before being replaced by the Mike 2, a redesign of its predecessor also featuring an 8008 processor, at the end of the first quarter of 1975. The Mike 2 was built around the 2-20 Console Board; the 2-1 CPU Board, which aside from the 8008 chip also contained a

The Mike family of microcomputers were sold as kits or as fully-assembled units and were designed around a stack of circuit boards, each measuring 5.5 by 7 inches (14 by 18 cm), separated by spacers. Each board carries a common bus through which each board can intercommunicate; the boards are

located on the PROM/RAM Board. An ultra-violet light also came shipped with the Mike 8 for easy erasure and reuse of the included blank EPROM. The Mike 8 was the first in the Mike family to be offered with an optional enclosure, so called the "black-box", to facilitate industrial applications and

Research's products became popular among hobbyists, who used their microcomputers as trainer platforms. The company soon embraced this demographic, designing products for buyers desperate to get their hands on a microcomputer in the burgeoning market.

Qwint sold its first trio of products under the new brand in April 1981, with the KSR-743 transmit-and-receive printing terminal, the KSR-744 teletype, and the receive-only RO-743. In 1982, the company expanded the KSR-744 teletype with two successor models, both supporting

changes, the bus remained the same, and users could replace the CPU Board of the Mike 2 with that of the Mike 3 if they so desired. The Mike 2 continued to be sold alongside the Mike 3 after the release of the latter. Both systems proved quite popular in 1975, with

providers. The following year, the company introduced the 780 series of teleprinters, which supported graphics. The new business proved lucrative enough for Qwint to employ 130 in 1984; the same year, the company moved into a 46,907-square-foot facility in
