Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://www.pcbway.com/ In this video we’ll follow on from the Backpack Quick Start. We’ll cover the differences in the newer Backpack Drive Plus (BPD+), and discuss the file layout on GitHub for both versions. We will also find out how to discover if the .BA programs for your M100 are really .DO, what problems this causes and how to avoid them. We will learn how to change the operating mode for machines covered in standard firmware, how to update firmware including updating to the special Epson version. We will then take a look at the adapters that are available to connect the Backpack with your computer. In an upcoming episode we’ll go into more advanced Backpack topics such as transferring files using XMODEM, writing BASIC programs to access Backpack feature and connecting the BPD to your PC and accessing it through VirtualT.

Description Follow along with Part 2 of this hard-fought battle to bring an old TRS-80 Model 100 laptop back from the brink. Not being familiar with this machine the diagnosis was lengthy but with the help of the good folks on the Model 100 mailing list and Saleae logic analyzer it did spring back to life. In Part 2 we finish the re-cap and replace the old NiCad memory backup battery with a modern Super Capacitor and learn a lot about the benefits and drawbacks of a super capacitor along the way. We also look at the bad RAM module to see if the fault can be diagnosed. If you have questions are comments, please leave them below.
