An almost insurmountable obstacle to portraying chess pieces on the screen without distorting their identity, color, or the color of the square upon which they're resting. Many strategies have been used to solve this problem but SFINKS has the least distortion of any TRS-80 chess graphics I've seen. If you are interested in a printout of the moves in your upcoming game, put your printer on line and the moves are printed out as they are played. If you put yourtape recorder on record and plug in...

Compiling the Load 80 directory is one of the last steps in getting 80 Micro to press. A scant few days before the magazine goes to the printer the editors decide exactly which articles will be in the issue. This leaves little time to decide on what will go onto the Load 80 tape. In May the mad rush caught up with us. We estimated we could fit 12 programs onto the cassette, and printed the Load 80 directory accordingly. A week later we had to cut FORE, PERSPECT, and TESTFILE the extreme length...
