Connections underway were slow-to-non-existent, and this time I took only my trusty iPad 2. Unfortunately the combination proved unwieldy for posting, and I had to go back to those posts now, recheck formatting and add some links; if you enjoyed the stories, you may want to re-read them. (I also fixed some errors.)
Part IV should be out Real Soon Now. In the meantime, you may wish to read this reasonably accurate article out about the Unitron Mac clone debacle which happened roughly at the same time.
