I just saw a great video on YouTube the other day in which a gentleman who goes by the name of Vintage Volts, and shows a method of connecting his Tandy TRS-80 Model 4D to a PC via its RS232 serial port and transfer software downloaded from the Web to use on a real TRS-80. I thought this was a very handy video as one of the most popular questions I am asked is how to get software from the Web onto a real TRS-80. This method applies to any TRS-80 model fitted with a serial board, and works pretty well. I’ve tried it with my Model I and 4P and it does work if you follow all the steps.
NOTE: the video is long (over 38 minutes), and extremely detailed, and aimed at a non-technical audience. The flip side is that technical type people may need to skip through various parts but do that at your own peril lest you miss an important point which prevents successful transfer of software to your TRS-80. Enjoy the video, and if you need an RS232 serial board for your Model I/III or early Model 4, drop me a line.
