I have the original book. It was written in assembly, but with very few macros.
It may also be known that many different excerpts from the book were published
in a few computer magazines that were in circulation at that time.
The orignial Sargon I was only rated about 1150 points on a 2 mhz Z80 machine,
ie. Radio Shack Model I or III. Sargon II on the other hand had a much faster
search routine, it could search at least one ply deeper and was rated about 1450
points on the same machine. I have both programs, and I have Sargon III which
was written for the PC's along wiht Sargon 4 and 5.
They used a static exchange evaluator for capturing pieces, that is the pieces
were loaded on a stack form the smallest to the largest and then were swaped
until one side of the other gained or lost points.

P.S.
The code was in Z80 assemble, but was readily convertable to 8080 coding.
