Nice! A good way to make the information available to everyone. Jeff Birt

I finally knew why my RS232 was unreliable and how to fix it. In my schematic transcript of the M100 I aim to add additional information for anyone working on that machine, so there are a few more annotations explaining things of what to look out for. I've now also updated the transcript to point to that bulletin in the RS232 corner of the schematic, so that anyone who comes across it can quickly see that there is a bulletin and verify with their machine.

Cheers, ' Henner.
