The FORTH/Assembler ROM Owner's Manual will be a big help. You can get it on the latest CD/DVD here.

There is also an excellent book entitled: "The Basic HP-71 Version 2.1" by Richard E. Harvey, which is very difficult to find. I have only seen two copies for sale on the auction site in eight years. It is particularly useful for assembly language programming of the 71B.

There is a "Saturn" document written for the 48/49 that starts at
a very basic level. Chapter III describes the Saturn.
The HP-71B version uses a sub-set of the 49 version Saturn.
You can find it here: Saturn Doc
