JS&A Computer Chess Mk 1

JS&A Chess Computer – Rebranded Novag Chess Champion MK I

In 1978, JS&A introduced the JS&A Chess Computer, a rebranded version of the Novag Chess Champion MK I. Although manufactured by Novag Industries Ltd., the unit was marketed exclusively by JS&A in the United States.

The JS&A Chess Computer used a program that closely resembled the earlier CompuChess software. This led to a well‑documented legal dispute between Data Cash Systems and Novag, alleging unauthorized copying of the original DCS chess program. The case highlighted the emerging intellectual‑property challenges in early computer‑chess development.

Technical Characteristics
Both CompuChess and the JS&A Chess Computer shared similar architecture:

• CPU: Fairchild F8 @ 1.78 MHz
• Memory: Approx. 2 KB ROM, 256 bytes RAM
• Input: Keypad entry (no sensory board)
• Output: LED indicators and simple move display
• Play Strength: Modest by modern standards, but competitive with other late‑1970s consumer chess computers

These machines represented the transition from electromechanical chess devices to fully digital microprocessor‑based systems.

Marketing Significance
JS&A’s catalogue was influential in popularizing early consumer electronics. Their marketing of chess computers included:

• National mail‑order campaigns
• “Challenge the Computer” promotional themes
• Positioning computer chess as both an educational tool and a technological curiosity

JS&A’s involvement helped introduce microprocessor chess to a broad American audience, even though the company itself did not design or manufacture the hardware.

Legacy

JS&A’s role in computer chess was brief but historically important. The company:

• Helped distribute one of the earliest commercial chess computers (CompuChess)
• Marketed a rebranded Novag unit that became part of a landmark software‑copyright dispute
• Demonstrated how mail‑order electronics firms contributed to the spread of early home‑computer technology

Today, JS&A’s chess products are of interest to collectors for their place in the evolution of dedicated chess computers and for their connection to the pioneering work of Data Cash Systems and Novag.

Made in Hong Kong.
