Heathkit H8Heathkit's H8 is an Intel 8080A-based microcomputer sold in kit form starting in 1977. The H8 is similar to the S-100 bus computers of the era, and like those machines is often used with the CP/Moperating system on floppy disk. The main difference between the H8 and S-100 machines is the bus; the H8 uses a 50-pin bus design that was smaller, more robust and better engineered electrically.
Electronic kitAn electronic kit is a package of electrical components used to build an electronicdevice. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions, and often a printed circuit board (PCB) or another type of prototyping board. There are two types of kits. Some build a single device or system. Other types used for education demonstrate a range of circuits.
Heathkit H11The Heathkit H11 Computer is an early kit-format personal computer introduced in 1978. It is essentially a Digital EquipmentPDP-11 in a small-form-factor case, designed by Heathkit. The H11 is one of the first 16-bitpersonal computers, at a list price of US$1,295, (equivalent to $6,392 in 2025) but it also requires at least a computer terminal and some form of storage to make it useful. It was too expensive for most Heathkit customers, and was discontinued in 1982.
Amateur radioNon-commercial use of the radio spectrumAmateur radio station with transceivers, amplifiers, and a computer for digital modes. On the wall are awards, certificates, and QSL cards from foreign stationsAmateur radio, also known as Ham radio, is the use of specific bands and frequencies within the radio spectrum for non-commercial communication, technical experimentation, self-training, recreation, radiosport, contesting, and emergency communications.
Edward Bayard HeathEdward Bayard Heath (November 17, 1888 – November 1, 1931) was an American Aircraft engineer.
AircraftAn aircraft or aerial vehicle is a vehicle that can fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, drones, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.
Electronic test equipmentElectronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.
Zenith Z-89The Z-89 is a personal computer introduced in 1979 by Heathkit, but produced primarily by Zenith Data Systems (ZDS) in the early 1980s. It combined an updated version of the Heathkit H8 microcomputer and H19 terminal in a new case that has room for a built-in floppy disk on the right side of the display. Based on the Zilog Z80microprocessor, it is capable of running CP/M as well as Heathkit's own HDOS.
High fidelityHigh fidelity (hi-fi or, rarely, HiFi) is the high-quality reproduction of sound. It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range.
Home audioHome audio refer to audio consumer electronics designed for home entertainment, such as integrated systems like shelf stereos, as well as individual components like loudspeakers and surround sound receivers. The evolution of home audio began with Edison's phonograph, transitioning from monaural to stereophonic sound in the 1950s and 60s when the term hi-fi emerged, highlighting sound accuracy and minimal distortion.

North DakotaU.S. stateState in the United StatesNorth Dakota ( ) is a landlocked U.S. state in the Upper Midwest, named after the indigenous Dakota and Sioux peoples. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland.
