Hello,

Well found, CC7.
Also I think that Bray Research Ltd. simply bought the rights to the program created by ICSL for the Chess King/Lansay Triumph ( "(C)1985ICSL" in ROM ).
Bray Research Ltd then supplied it with "(C)1988Bray" signature to Yeno for the 301XL.
It would be interesting to know the signature in the Counter Gambit ROM and its date.

Cordially.
