GeoPDF refers to map and imagery products created by TerraGo software applications.
 GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications.
 However, GeoPDF products conform to published specifications including both the OGC best practice for PDF georegistration as well as Adobe's proposed geospatial extensions to ISO 32000, making them readable by applications such as Adobe Acrobat, Adobe Reader, Avenza PDF Maps, Global Mapper, and others.
 GeoPDF products often include other advanced PDF features such as layers and object data which can add significant GIS functionality to the file, particularly when used with the TerraGo Technologies plugin to Adobe Reader or other TerraGo clients.
Bowman v. Monsanto Co., 569 U.S. ___ (2013) was a United States Supreme Court patent decision in which the Court unanimously affirmed the decision of the Federal Circuit that the patent exhaustion doctrine does not permit a farmer to plant and grow saved, patented seeds without the patent owner's permission.
 The case arose after Vernon Hugh Bowman, an Indiana farmer, bought transgenic soybean crop seeds from a local grain elevator for his second crop of the season.
 Monsanto originally sold the seed from which these soybeans were grown to farmers under a limited use license that prohibited the farmer-buyer from using the seeds for more than a single season or from saving any seed produced from the crop for replanting.
 The farmers sold their soybean crops (also seeds) to the local grain elevator, from which Bowman then bought them.
 After Bowman replanted the crop seeds for his second harvest, Monsanto filed a lawsuit claiming that he infringed on their patents by replanting soybeans without a license.
 In response, Bowman argued that Monsanto's claims were barred under the doctrine of patent exhaustion, because all future generations of soybeans were embodied in the first generation that was originally sold.
Exidy was one of the largest creators of arcade video games during the early period of video games, from 1974 until at least 1986 (when "Chiller" was released).
 The company was founded by H.R. "Pete" Kauffman.
 The name "Exidy" was a portmanteau of the words "Excellence in Dynamics."
Zenith Data Systems (ZDS) was a division of Zenith Electronics founded in 1979 after Zenith acquired Heathkit, which had, in 1977, entered the personal computer market.
 Headquartered in Benton Harbor, Michigan, Zenith sold personal computers under both the Heath/Zenith and Zenith Data Systems names.
 Zenith was an early partner with Microsoft, licensing all Microsoft languages for the Heath/Zenith 8-bit computers.
 Conversely, Microsoft programmers of the early 1980s did much of their work using Zenith Z-19 and Z-29 CRT display terminals hooked to central mainframe computers.
 The first Heathkit H8 computer, sold in kit form, was built on an Intel 8080 processor.
 It ran K7 audio-tape software, punched tape software (with puncher/reader H10) and HDOS (Heath Disk Operating System) software on 5¼" hard-sectored floppy disks.
 The CP/M operating system was adapted to all Heath/Zenith computers, in 1979.
 Next, the early Heath/Zenith computers (H88/H89 and Z-89) were based on the Z80 processors and ran either HDOS or CP/M operating systems.
HDOS is an early microcomputer operating system, originally written for the Heathkit H8 computer system and later also available for the Heathkit H89 and Zenith Z-89 computers.
 The author was Heath Company employee Gordon Letwin, who later was an early employee of Microsoft and lead architect of OS/2.
Heathkit's H8 is an Intel 8080-based microcomputer sold in kit form starting in 1977.
 The H8 was similar to the S-100 bus computers of the era, and like those machines was often used with the CP/M operating system on floppy disk.
 The main difference between the H8 and S-100 machines was the bus; the H8 used a 50-pin bus design that was smaller, more robust and better engineered electrically.
 The machine also included a bootstrap ROM that made it easier to start up, including code for running basic input/output and allowing input through a front-mounted octal keypad and front panel display instead of the binary switches and lights used on machines like the Altair 8800.
 The H8 was a successful design but required a separate terminal to be truly useful; Heathkit introduced several terminals as well.
 A successor model, the "All-in-One" Heathkit H89, combined a Z-80 processor board and a floppy disk drive into the cabinet of an Heathkit H19 terminal.
 This model also was sold in fully assembled form as the WH89.
 These were later sold by Zenith Electronics with their name on the front as the Zenith Z-89.
Omni Consumer Products, founded in 2006 by graphic designer Pete Hottelet, is a company that creates "real-world" versions of certain products created in movies.
 The company takes its name from the fictional corporation of the same name featured in the "RoboCop" movie and television franchise.
 The company's products include a "Brawndo" beverage inspired by "Idiocracy", "Stay Puft Caffeinated Gourmet Marshmallows" inspired by "Ghostbusters", and a "Tru Blood" beverage inspired by HBO's "True Blood" series.
 The company also has licensed the rights to produce and market "Sex Panther", a Eau de Cologne in "".
 For a few months in 2009, Omni Consumer Products was a sponsor of Kevin Smith and Scott Mosier's podcast, SModcast.
Eagle Family Foods Incorporated, was an American producer of food and beverage products created in 1997 by employees of the Borden Milk Products division of Borden, Inc., which had sold its condensed milk line.
 The company was named after the condensed milk created by Gail Borden in 1853.
The J.M. Smucker Company acquired Eagle Family Foods Incorporated and its brands and products in May 2007.
The White Family Rotary or White FR was the first sewing machine produced by the White Sewing Machine Company using a rotary hook bobbin driver.
 It joined the successful White Vibrating Shuttle on White's expanding product line and eventually eclipsed it.
 It was originally sold as a treadle with cabinet or as a hand-crank with carrying case; later, add-on electric motors with foot or knee control were available pre-installed or as a field upgrade.
 Typical cost for this machine as a treadle with a cabinet was USD65 in 1909, which is about USD1532 adjusted.
The still room is a distillery room found in most great houses, castles or large establishments throughout Europe dating back at least to medieval times.
 Medicines were prepared, cosmetics and many home cleaning products created, and home-brewed beer or wine was often made.
 Herbs and flowers from the kitchen garden and surrounding countryside were preserved for flavoring food and processed into what today we call essential oils, and infused or distilled, or brewed (etc.) as required to make rose water, lavender water, tinctures, peppermint-based ointments, soaps, furniture polishes and a wide variety of medicines.
 The still room was a working room: part science lab, part infirmary and part kitchen.

Question: What type of machine, such as the Heathkit H8 which was originally sold in 1977, is required by the products created by Exidy from 1974 until 1986?
Answer: microcomputer
