I do still have them. No, I wont publish the notebook that contains the
collected wisdom. I did this a lot of years ago.

My $.02 2901 was an ok device but slow and turned out to the the
speed limiter. Also the microcode for was a pain! Never did a stack
cpu though the PDP-11 does that very well as is.
