Basic was created at MIT and Bell labs and expanded on by Keremy and Kurtz and introduced to their students at Dartmouth on the 1st of March 1964. This was the first public appearance of 'READY>'. Gates and Allen (not to be confused with Burns and Allen);-) wrote an updated version in 1975 for the MITS Altair. Gates went on to write Microsoft Basic that appeared in the ROMs of over 50 different machines to become a defacto standard. At about same time, other Basic Authors included LiChen Wang (Tiny Basic, I did a later Z80 version of this that I called Z8TBasic), Steve Leininger (Radio Shack level I), Steve Wozniak (Apple Integer Basic), and Gordon EuBanks (Basice and CBasic). Now if there is a Copyright infringment on the Basic Language Commands, then surely all the above people must tbe guilty. And this was all before 1980. As the Parallax Stamp Commands are an extension of the original Basic, perhaps they could be as guilty as myself and Bill Gates. :) Don McKenzie don@dontronics.com http://www.dontronics.com SLI, the serial LCD that auto detects baud rates from 100 to 125K bps.
