The author reported that when he needed to purchase such a computer quickly he did so at a local store for $ 6000 in cash, and cited it as an example of "what the state of the art is at present ... as a mass-produced product". By early that year Radio Shack, Commodore, and Apple manufactured the vast majority of the one half-million microcomputers that existed. As component prices continued to fall, many companies entered the computer business. This led to an explosion of low-cost machines known as home computers that sold millions of units before the market imploded in a

There also seems to have been a Q1 model with an enclosure, printer, and display identical to that of the second-generation Lite/MicroLite, but lacking both floppy drives; and yet another, with a slightly modified case, which lacked both the integrated printer and floppy drives entirely. (The former of these two was incorrectly labeled as a first-generation 1972 Q1 when a unit of this model was found in early 2024.)

Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
