Excalibur LCD Chess, (Excalibur 375-1 LCD Computer Chess)
a dedicated travel chess computer by Excalibur Electronics, released in 2000 [2].

The program and the new housing was developed and designed by Ron Nelson during his sabbatical in late 1999 [4].
The 4-bit program applies sophisticated PV move and killer move ordering heuristics [5],
