Ken, if you have time, an annotated disassembly of MADTEST (microcoded alto diagnostic) would be a good thing to have once you get the diag pack booted. It is the diagnostic that pounds the micromachine the hardest, and there is some magic in there that neither Josh nor I have had time to figure out, like how it knows that the ACSOURCE rom is old or new.
