Early Programming Books

TYDAC (TYpical Digital Automatic Computer) is very much an instruction set
of its time.

Memory is 2000 words of ten decimal digits and sign.
Words are either numbers or instructions.
I/O is punch cards, special typewriter, or a paper-tape reading device on
the typewriter.
Four magnetic tapes are assumed as auxiliary memory.
ALU includes an Accumulator (11 digits + sign) and Multiply-Quotient (10
digits + sign).
Instruction set includes floating-decimal add, multiply, and divide.
46 instructions (out of a possible 100) are defined.

Paul,

I assumed that was the case, but the inclusion of the Wilkes book confused
me. 
I think there really is a spectrum of books, so say pre-1955 all books
assumed the reader had little knowledge of programming. 
For example the MK1 guide I pointed you to is V2. Its rumoured that Turing
wrote V1 and no one could understand it but I think it more likely the
machine changed.
I also looked at the IBM 701 manuals and they too have some generic info at
the front. 
However I also wonder what the earliest books were like.

he has done a lot of research on early computing, and might know more.)
