Focal on the 6502, a page on this small language, originating for Digital Equipment.
A small interpreter (about 5K) for a convenient interpreted language. Floating point 9 digit accuracy. At least two versions were distributed around 1977, one by Aresco, called “Focal V3D” and another by the Program Exchange as representative of the Denver 6502 Group, often called “Focal-65E”
Latest addition is a reconstruction of the source, by Wayne Wall of the Denver 6502 Group in 1977, of Focal V3D for the TIM to binary, and a port to the KIM-1.
Based upon a listing of the TIM Focal-65 from 1977 and a Focal-65 User manual, repaired and cleaned up.
And that enabled the reconstruction of the soource Focal-65 V3D as distributed by Aresco!
