One of the photos of the PDP 8/A 400 came from this Herb Johnson page,
which is a diary of what I'm going to be doing after I true up the card
cage.
Excellent looking diary of what to check with the unit I have. Hopefully
with less drama and more things checking out.

I also don't know if I will ever use my darkroom again, and have Omega D2,
other enlargers, print washers and dyers, etc that I don't need.
