About
The Source was B & H Computers' big technical guide to the Einstein, sold in 1990 at sixteen pounds for the book, twelve pounds for the disc, or twenty five pounds for the two together.
The library holds the book. The disc is the part we are missing, and on a technical book the disc is where the working code lives.
Possibly Online Elsewhere
Tatung Einstein Reborn links a file named source.zip in its software area. We have not examined it and cannot say whether it is this disc.
Can You Help?
If you have the disc that came with The Source, please get in touch. We would image it, send you the images, and credit you here. We would also be glad to compare page counts with anyone holding a different printing of the book.
