I haven't been following the discussion, so sorry if I missed a bunch,
but I think I have that book from a plotter class I took back in the
70's. Punched cards on a 360 in assembly language calling and called by
fortran programs. Plotter was a small, desktop sized, drum with
continuous feed paper and mag tape input, and it was pretty old in 1975.
Send me an email directly and I can "start" looking for it in storage.
Exotic commands I recall include, pen up, pen down, move (x,y).
