No major progress this summer on the Disk ][ interface - too many distractions . The USB interface is pretty difficult, though I do have the Disk ][ interface recognized by a PC as a disk interface.
Beyond the usual family activities and homeowner maintenance projects, a few other projects have interfered, including constructing the microphone preamp that I needed to improve the quality of my podcast and research on the City Point and Army Line Railroad. I also just received good scans of an original Apple 1 circuit board, which may be the catalyst that kick starts an Apple 1 replica effort. Too many projects, not enough time :-(.
