The kids from NYC Resistor have made a discovery of interest to veterans who have lived the first years of Apple’s life. It turns out that they have found black and white images of some Macintosh developers encrypted in the source code of the Mac SE ROM . Above you have one of the pictures found, with a quality based on the density of black and white points.
This point system makes it easy to hide the image in the source code, since a white and a black point can be very easily translated into the binary system. The explanation they give us in the source is very technical, but basically they have had to decipher hexadecimal code from the Mac SE’s ROM and create functions in more modern code to be able to understand it well.
Basically, there’s a source code function that draws those images in black and white points at a resolution equivalent to that of the Mac screen. In addition, with the images, came the date of November 20, 1986 and a string of characters that they have not yet been able to decipher (if it really hides some data):
We leave you with the rest of the images that have been found.
