Byte-Back Co

BYTE-BACK started producing peripherals for the Sinclair computer in 1981.

Their first product, a relay controller, was used by customers to control and automate projects.

The original owner closed the company in the mid-1980s. David Leech, a former employee, purchased the company and continued to sell existing inventory.

In the late 1980s, Leech introduced multifunction controllers for the IBM PC.
