1947 Heathkit ad featuring the 5-inch oscilloscope. Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath ...
Two Heathkit Grid Dip Meters with a set of tuning coils. The dip meter can be used either to measure the relative power lost to a nearby circuit (in which case the amplitude shown on the meter "dips") or to measure the relative power absorbed from a nearby powered circuit (in which case, the meter amplitude peaks). In either mode of operation ...
Heathkit began a program to develop their own kit that would be much superior to the Altair, [2] which was known to have poor reliability due to a number of design decisions. [ a ] The concept of building a computer remained a heated issue in the company, but started moving forward after one engineer stated "All right, we'll build a computer.
Zenith Data Systems Corporation (ZDS) was an American computer systems manufacturing company active from 1979 to 1996.It was originally a division of the Zenith Radio Company (later Zenith Electronics), after they had purchased the Heath Company and, by extension, their Heathkit line of electronic kits and kit microcomputers, from Schlumberger in October 1979.
A dual-beam oscilloscope was a type of oscilloscope once used to compare one signal with another. There were two beams produced in a special type of CRT . Unlike an ordinary "dual-trace" oscilloscope (which time-shared a single electron beam, thus losing about 50% of each signal), a dual-beam oscilloscope simultaneously produced two separate ...
Heathkit'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/M operating system on floppy disk.
Oscilloscope showing a trace with standard inputs and controls. An analog oscilloscope is typically divided into four sections: the display, vertical controls, horizontal controls and trigger controls. The display is usually a CRT with horizontal and vertical reference lines called the graticule. CRT displays also have controls for focus ...
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.
