Ron Nelson spent 9 months developing a new 4 Bit chess program which became the foundation for many future Excalibur models as well as its continued use by Excalibur's successor EB Electronics. The first 4 Bit Model 375 Excalibur LCD Chess was launched in the year 2000. This program can also be found inside many chess computer models sold by other companies such as Radio Shack.
This 4 Bit program seems to be per Nelson's comments an even further slimmed down version of the original Nelson H8 program, compressed into this much smaller hardware and trimmed with many of the features of the original stronger H8 program removed in order to squeeze a workable chess program into the lesser ram space available on the 4 Bit hardware. This included removal of many of the more sophisticated chess routines used in stronger chess programs such as Nelson's Attack Bit Map Tables, much smaller opening books, removal of any pondering routines and excess search routines.
Nelson commented he had a great interest in developing a capable program suitable for any beginning or hobby chess player and thereby finding larger outlets of distribution for the Excalibur chess products.
Excalibur e-Chess Express is a fun program, with its 8 fast response levels it is ideal for most casual players who are interested in a quick game of chess. Excalibur LCD Keychain Chess was one of the many creations that followed as a result of this nine month period of new program development in 1999.
