Apple 1 Application Notes


Apple 1 Basics

There were many versions of Apple 1 Basic provided by Apple in the early days. There was just Woz and SJ and Woz was writing Basic while the computers were being sold. When someone got a copy from SJ it was just the last stable version from Woz. I bought my Apple 1 at a Byte shop in mid 1976 and I got 4 different versions of Basic over the next 6 months or so. I labeled them version A through D. Version A did not even have an INPUT statement so about all you could do is print “HELLO WORLD”. Version B added the INPUT statement, Version C added Arrays and Version D added PEEK and POKE. I have copies of C and D but have not been able to find any earlier. The Huston brothers got a copy of Apple 1 Basic in late 1977 or early 1978 when they were employees at Apple that includes a checksum program and I presume that was the last version. By late 1976 and early 1977 Woz was focused on the Apple II.
