Wozniak's references for BASIC were a copy of "101 BASIC Computer Games" and an HP BASIC manual. He did not know that HP's BASIC was very different from the DEC BASIC variety used in "101 Games", which was also the basis of Microsoft BASIC for the Altair. Based on these sources, Wozniak began sketching out a syntax chart for the language. The design initially included floating-point support, but still hoping he might publish the first BASIC on the 6502 and become "a star", he decided to abandon floating-point and write a separate integer math system to save a few weeks programming time.
