Super Constellation (Nickname Super Connie), a dedicated chess computer with a 8-bit 6502 4Mhz CPU, 56 KB ROM and 4 KB RAM, manufactured and market in 1984 by Novag, running a program developed by primary author David Kittinger, supported by chess master Scott McDonald. It was the enhanced version of the Constellation and likely Novag's most successful computer, and famous for its entertaining, aggressive, speculative and "human like" playing style, often credited to its pre scan heuristics (PSH).

=Innovations= David Kittinger and Scott McDonald in their report on Constellation and Super Constellation playing the 1983 U.S. Open : The Novag Constellation programs represent a significant evolutionary step in the development of microcomputer chess programs. The program represents the first commercial implementation of the attack map / offset map move generating strategy proposed by former World Chess Champion Mikhail Botvinnik and subsequently refined by myself for faster move generation as pieces come off the board.

A second departure from other commercial programs has been the simplification of the evaluation function as applied to the end nodes of the tree search. The programs instead rely heavily on specific chess knowledge which is concentrated into a special preprocessor which interfaces to the tree search primarily through the scores associated with specific ply-one moves. This ides of a ply-one move preprocessor was originally implemented in the program Tech by James Gillogly in the late 1960's. Although Tech only achieved a high 1400 rating running on a large computer, the strategy has certain appeal. First, chess tree searching has become very efficient, and second, the interaction problems associated with putting ever increasing amounts of chess knowledge in the tree become formidable. It has become apparent to that this rather simple approach might contain the structure of a master level microcomputer program.

The 1981 performance rating achieved at the 1983 U.S. Open by the Novag Super Constellation 32K program running on a 3MHz 6502 supports my decision. ...

The Super Constellation was an early version of the soon to be announced commercial product.

=Tournament Play= Super Connie participated at the WMCCC 1983 in Budapest, and achieved the strong shared second to fourth place. During the Hong Kong human Blitz tournament March 1984, Super Constellation got 19/28 only playing Black, with 5 points versus International Masters in the 2355 to 2474 range, and was spontaneously called Blitz Monster, also competing at the WMCCC 1985 under that name.
