Yup, I've got that book.

place a fully transistorized and 19 transistors retro labels on them :)

Not quite. Or at least, the processes that work well are kept secret, applied
to small displays -- not necessarily easy in a garage shop. But for some things
where short lifetime is OK, there are recipes used

Of course a discrete logic wire-wrapped computer is cool. There is no
question on that one. But
Michael,
I am in the same boat as you we also use altera software because our
designs here at MRA Tek are so demanding and complex and need to be in
such a small physical volumn that even if descrete components could
handle the computational speed that we need (which they don't) we
couldn't
