Chess Champion Delta-1
SciSys Chess Champion Delta-1 1 20 x 20

The Scisys Chess Champion Delta-1 is  the same model as the Novag Chess Champion Delta-1, which is more numerous. With the Chess Champion Pocket Chess, Chess Partner 2000 and Chess Champion Super System III the Delta-1 was one of the chess computers released by both Novag and SciSys at the same time. The SciSys examples can be identified by the stickers added to the boxes and manual.

There are similarities between the PCB components of the Delta-1 and those of the Novag Chess Champion Mk I  and it is possible that release of the Delta-1 was held back pending the result of the CompuChess copyright court case and appeal (see SciSys and Novag: The Early Years). That might explain the box being dated 1979 but the chess computers not being released until late 1980.

With a current Wiki Active Chess rating of only 698 Elo the Delta-1 props up the Active table. The rating is very close to that of the Novag Chess Champion Mk I  rating of 723 Elo. Therefore the programme could be the same as in the Mk I, or possibly the work of Mike Johnson.
