Documentation, OSIO Newsletter Volume III, Number 9

Description
Ohio Scientific Inc. (also known as Ohio Scientific Instruments) was an American computer company located in Hiram, Ohio. It built and sold microcomputers from 1975 to 1981 when the company was sold to M/A-Com Inc. in Massachusetts.
In 1976, OSI sold for $99, a computer “trainer” kit consisting of the microprocessor, the MOS 6502, and enough circuitry to communicate with the processor. The buyer had to build it and add a terminal display. Later models made by the company were the OSI Model 500, Challenger III, Superboard II, Challenger 1P, Challenger 2P, Challenger 4P, and the Challenger 8P.
In the 1970s and 1980s numerous computer societies and users groups were established to share information. Some took a general approach, while others focused on a computer brand, operating system, or programming language. This newsletter is from an OSI user group based in Ellicott City, MD.
OSIO Newsletter Volume III, Number 9 October 1981 for the VA/DC/MD OSIO group [duplicate issue number]. Articles on the front page include “OS-65D Notes” and “Add Named Addresses To GOTO and GOSUB.” The document consists of four double-sided pages folded in half for mailing.
