Designed by Steve Wozniak, Steve Jobs and Ronald Wayne and tested in series in the Jobs garage, the Apple-1 was the first Apple product put on sale in April 1976. The commercialization of this microcomputer, one of the very first, was accompanied by a great mystery.
On each motherboard was indicated an inscription in black felt.
A kind of serial number.
Where does this entry come from?
Steve Wozniak has always assured not to be the author of the serial number, just like Steve Jobs.
The two accomplices were however logical suspects: Steve Wozniak as the designer of the CM of the Apple-1 while Steve Jobs participated in the assembly.
Paul Terrell, the owner of the Byte Shop and first sponsor of fifty Apple-1s, claims to have nothing to do with it either.
Who had marked these motherboards?
Achim Baqué, holder of the Apple I register which lists the list of all the computers concerned, looked into the subject in order to solve this mystery.
To do this, he turned to PSA, one of the world's leading handwriting authentication services.
Daniel Kottke (a close friend of Steve Jobs) for his part sent handwritten documents of Steve Jobs to the authentication service so that he could compare as best as possible.
And the culprit is?
After three months of extremely detailed analysis, PSA has made its final conclusion: Steve Jobs is indeed the sole author of the serial number written by hand on each Apple-1 motherboard.
In other words, the first microcomputers from Apple are all "signed" Steve Jobs.
