Welcome to the Online Q1 Computer Museum!


Q1 Corporation was a computer company established in August 1969 by Daniel Alroy,
a New York investor and evaluator who foresaw the incredible utility of LSI microprocessors.
In the same year the first 8-bit microprocessor was released, 1972, Q1 Corporation delivered a
complete business microcomputer system - the Q1/T - utilizing the 8008 and floppy disk drives
to the U.S. defense contractor Litton Industries, predating other complete business microcomputer systems
by several years. Unlike later hobby systems like the Altair 8800, the Q1 was marketed directly towards end users.

This online museum is dedicated to preserving and documenting the rather unknown history of the Q1 Corporation,
from its conception at the turn of the 1970s to its eventual fall into obscurity by the mid-1980s.

Other Forgotten Early Microcomputers

There are several other very early microcomputer systems, mostly predating the Altair 8800 from 1975,
which are very significant, yet poorly documented. I have attempted to rectify this to some extent below.
