Vintage Computer Advertisements from the late 1970s

IMSAI Megabyte Micro ad from 1977


IMSAI or IMS Associates, Inc, was an early success story in the microcomputer industry because they immediately recognized the success of the Altair 8800 and developed a similar unit that has become known as the first clone computer.

From the advertisement: Until today, the largest memory you could fit and address in a single microcomputer CPU was 65K. Now, IMSAI presents an incredible memory system for micros 16 times more powerful that yesterday’s best. Imagine, a full megabyte of power from sixteen 65K RAM boards.
