Well, I finally got another Model 4 project done. I think I have been working on this for about 2 years. Its an external USB floppy disk for Windows. Currently I can create and read Model 4 MM CP/M images with a .Net app running on Windows 10. Its all pretty simple and low cost. I have included some pictures so you can get the idea of how it all goes together. The first picture shows the finished drive with Arduino Due, Model III floppy controller (I think) and floppy drive. The setup can easily replicate MM CP/M disks. The next job is to get it working with Matthew Reeds TRS32 emulator. Once complete I will no longer need my tweener setup to create Model 4 floppies.
The next picture shows how perilous it is doing hardware development at my house. Notice the chewed on wires. The cat mainly liked the jumpers from the logic analyzer but it still led to hours of troubleshooting until I realized the wires were cut.
