MITS Disk Extended BASIC Version 4.1. Palo Alto Tiny BASIC emerged out of the Tiny BASIC movement started by People's Computer Company and taken up by the Homebrew Computer Club. Below are two screen capture of the emuStudio-039. This is my demonstration of the Altair 32 (www.altair32.com) Emulator running on Windows XP. The Altair was the first computer released to the public in January 1975 (check here for history) by MITS, it was a very ugly machine that could only be coded in machine/assembly language by flipping switches.Basically saying: "Real Programmer's Don't Need Keyboards!" Bill Gates & Paul Allen wrote Altair BASIC which was Microsoft's first product. MITS Altair8800 . I have faithfully followed the program order, and the code naturally divides into three sections - the Interpreter, the Maths Package, and Initialisation.
