Inmos publish two documents that give this information:

The preliminary datasheet for the IMS T800 transputer ref 42 1082 00
gives the full set of op codes with mnemonics e.g.

Function Code  Memory Code  Mnemonic Cycles Name
        3        3X             ldnl   2    load non-local
        4        4X             ldc    1    load constant

The transputer instruction set - a compiler writers' guide ref 72 TRN 119 02
gives details of the instruction set. e.g.

ldc #4_  load constant
Areg' = Oreg
Breg' = Areg
Creg' = Breg
Oreg = 0
Iptr' = NextInst

The second of these should be essential reading for anyone working with
transputers.

-----------------------------------------------

BTW I have written some occam libraries for the standalone occam
compiler (not the TDS) that provide an interface similar to the C
stdio calls (including printf!). Would anyone like me to post the source?
It is several hundred lines of occam. I also have a mandelbrot program
that runs on a single transputer and uses the stdio.occ library to
write the result to a file.
