Main Topic: The TRS-80 Model II

At this point in the podcast run, we are still in the late 1970’s time frame, and the TRS-80 Model II falls into that time frame for its release.  As usual, we’ll cover the history, technical specs, peripherals, Web sites, books, emulation and much, much more.  I am joined by special guest host Myles Wakeham who will help me cover this machine.  But first, I’ll cover new acquisitions, news, feedback, and an interview with Myles before diving into the TRS-80 Model II.
