Interview


Buzz Murphy


Pete interviews former Tandy Radio Shack Marketing Manager Buzz Murphy. Buzz Murphy worked for Tandy Radio Shack in the late 1970s and early 1980s. He joined the company just before the TRS-80 was introduced so he was able to participate in one of the great success stories of the early personal computer era…the TRS-80 Model I. Buzz was a computer marketing expert and divisional manager at Radio Shack Computer Centers and so he offers a different perspective of the TRS-80 story from what you may have heard before.

Episode 30 - Lots of Acquisitions and Rick Papo


Description


Spring is in the air at Trash Talk headquarters, so we’ve been itchy to make quite a few acquisitions lately that we discuss, including a long weekend drive to Chicago.  We also introduce a new TRS-80 search engine that should prove to be a highly valuable resource to the TRS-80 community.  Then, we do some eBay shopping for TRS-80 computers and related items.  Finally, we interview TRS-80 programmer Rick Papo.  Rick was the author of several important reference books for the TRS-80 which included reverse engineered and highly documented system source code.  These are invaluable references for the modern day Z80 assembler programmer.
