I remember ogling magazine ads for these games back in the early- to mid-1980s. Never did get to play them on a computer, but later played the NES version of the first game, which was underwhelming. Apparently the sequel was ported too, but only in Japan.
I must say there's something uncommonly nostalgic about seeing 8-bit, low-color renditions of beach scenes. The Tandy Color Computer only had four colors in hi-res mode -- blue, orange-red, black, white -- and a few of its graphic adventure games started out on the beach or in the desert. The sky was blue, while the sand could be done pretty well with intermixed red and white in various patterns. Ah, those were the days.
