This is a '''list of early microcomputers''' sold to hobbyists and developers. These [[microcomputer]]s were often sold as "[[Do it yourself|DIY]]" kits or pre-built machines in relatively small numbers in the mid-1970s.  These systems were primarily used for teaching the use of [[microprocessor]]s and supporting peripheral devices, and unlike [[home computer]]s were rarely used with pre-written application software. Most early micros came without alphanumeric keyboards or displays, which had to be provided by the user. [[Random-access memory|RAM]] was quite small in the unexpanded systems (a few hundred bytes to a few kilobytes). By 1976 the number of pre-assembled machines was growing, and the 1977 introduction of the "Trinity" of [[Commodore PET]], [[TRS-80]] and [[Apple II]] generally marks the end of the "early" microcomputer era, and the advent of the consumer home computer era that followed.
