We have this wonderful sewing machine from the mid eighties, a New Home Memory Craft 6000 - instruction book is available here. The brand is also known as “Janome”. This machine can stitch letters and symbols using microprocessor control, sewing “emojis” before that word was widely known. When it was recently powered on after a few years sat idle, it was completely inert (apart from the work light). A local sewing-machine repair place took a look, said it was blowing fuses repeatedly, indicating a fault on one or other of the PCBs.
