The next day the Altair with 7 kB had finally passed its memory test and Allen had their BASIC interpreter on a paper tape Bill Gates had created just before Allen left Boston. It took almost 15 minutes for the Teletype to load the program into the Altair then the Teletype printed "MEMORY SIZE?" Allen entered 7168 and the Teletype printed "READY". Both Allen and Roberts were stunned their software and hardware actually worked. They entered several small programs and they worked. The BASIC interpreter was not complete and crashed several times, but Roberts had a high level language for his computer. Roberts hired Allen as Vice President and Director of Software at MITS. Bill Gates also worked at MITS; the October 1975 company newsletter gives his title as "Software Specialist".
